Fabspeed Exhaust

Fabspeed Deluxe X-50 Style Tips.

The Fabspeed Deluxe X-50 Style Exhaust Tips are premium replacement exhaust outlets designed for Porsche 996 Turbo models from 2000–2005.

Fits:

• Porsche 996 TURBO 2000-05

Inspired by the distinctive X50-style exhaust appearance, these tips provide a clean, performance-focused upgrade for the rear of the 996 Turbo. They are designed as bolt-on replacements and can be fitted to factory or compatible aftermarket exhaust systems.

Manufactured from high-quality 14–16 gauge T304 stainless steel, the tips are engineered to withstand exhaust heat, moisture and everyday road exposure while providing a durable, high-quality finish. Fabspeed also specifies simple DIY installation.

What This Product Does:
Exhaust tips form the visible final section of the exhaust system. They provide the finished outlet through which exhaust gases exit at the rear of the vehicle while also playing an important role in the appearance of the exhaust system.

The Fabspeed Deluxe X-50 Style Tips replace the original exhaust outlets with a more distinctive performance-inspired design.

Their main functions and benefits include:

• Providing a finished outlet for exhaust gases
• Upgrading the rear appearance of the Porsche 996 Turbo
• Replacing ageing, damaged or deteriorated original exhaust tips
• Providing durable stainless-steel construction
• Maintaining proper positioning of the exhaust outlets
• Allowing installation on factory or compatible aftermarket exhaust systems
• Creating an X50-inspired performance appearance

These exhaust tips are primarily an appearance and durability upgrade rather than a significant engine-performance modification.

Symptoms Of Wear Or Failure:
Exhaust tips are constantly exposed to high temperatures, condensation, moisture, exhaust deposits and road contamination. Over time, the original tips can deteriorate.

Common signs that replacement may be required include:

• Rust or corrosion
• Surface pitting
• Heavy staining or permanent discolouration
• Peeling or deterioration of the original finish
• Dents or impact damage
• Scratches that cannot be polished out
• Loose exhaust tips
• Rattling or vibration
• Cracked mounting points or welds
• Tips sitting unevenly or incorrectly aligned
• Excessive soot around the connection point
• Exhaust tips contacting the bumper or surrounding trim
• A tired appearance that cannot be restored through cleaning or polishing

Severe corrosion can eventually weaken the tip or its mounting area enough for the outlet to become loose.

Why Replacement Matters:

• Worn exhaust tips can affect both the appearance and security of the exhaust outlet.
• A loose or damaged tip may vibrate or rattle while driving and can move sufficiently to contact the rear bumper or surrounding trim. If corrosion progresses far enough, mounting areas can weaken and the tip may no longer remain securely attached.
• Replacing deteriorated tips helps restore the correct exhaust outlet positioning and gives the rear of the vehicle a cleaner, more finished appearance.
• Where the remainder of the exhaust system remains in good condition, replacing only the tips is also a practical way to refresh the exhaust without replacing silencers, catalytic converters or other major components.
• For owners seeking a more distinctive appearance, the Fabspeed X-50 Style Tips provide an easy bolt-on upgrade while retaining compatibility with factory and suitable aftermarket exhaust systems.

Fabspeed Link Comp. Pipes.

The Fabspeed Porsche 996 Turbo Cat Bypass Pipes are high-performance exhaust components developed for the Porsche 911 Turbo (996), designed specifically for use with compatible existing Fabspeed exhaust systems.

Fits:

• Porsche 996 TURBO 2000-05

Manufactured from premium 14–16 gauge T304L stainless steel, these catalyst-bypass pipes replace the sport catalytic converter sections of the Fabspeed exhaust with straight-through pipework.

Their purpose is to provide a less restrictive exhaust path, producing a more aggressive exhaust note and supporting improved exhaust gas flow from the Porsche 996 Turbo's twin-turbocharged 3.6-litre flat-six engine.

By removing the catalytic converter elements from the exhaust path, the bypass pipes eliminate a source of exhaust restriction and create a more direct route for gases leaving the turbochargers.

Fabspeed designs these pipes for owners seeking a more extreme, motorsport-oriented exhaust configuration.

The system uses CNC mandrel-bent stainless steel tubing to provide smooth internal pipe geometry, consistent exhaust routing and durable construction.

Fabspeed describes the pipes as a direct bolt-on alternative to the corresponding catalytic converter sections in its compatible exhaust systems.

A key feature of this product is its modular compatibility with existing Fabspeed exhaust components, including suitable Maxflo and Supersport X-Pipe configurations.

However, these are not universal catalyst replacement pipes.

They do not fit directly onto the original Porsche factory exhaust or exhaust systems manufactured by other aftermarket suppliers.

Fabspeed lists a weight reduction of approximately 25 lb (11.3 kg), although the precise saving will depend on the configuration being replaced.

The manufacturer also states that the pipes can improve power delivery and throttle response, but does not publish a confirmed horsepower or torque increase for this standalone product.

What This Product Does:
The Fabspeed Cat Bypass Pipes replace the catalytic converter sections of a compatible Fabspeed Porsche 996 Turbo exhaust.

In a conventional catalytic exhaust, exhaust gases pass through a catalytic converter containing a coated internal substrate.

The converter treats pollutants in the exhaust gases, but its internal structure also creates a degree of flow resistance.

Fabspeed's bypass pipes replace those sections with straight-through tubing, eliminating the catalytic converter substrate from the exhaust path.

The main functions and benefits include:

• Creates a Straight-Through Exhaust Route: Replaces the existing Fabspeed sport catalytic converter sections with unrestricted pipework.
• Reduces Exhaust Restriction: Removes the catalytic substrate from the exhaust gas path.
• Supports Increased Exhaust Flow: Provides a less restrictive route for gases leaving the turbochargers.
• Enhances Motorsport Exhaust Sound: Produces a louder, sharper and more aggressive exhaust character.
• Improves Performance Potential: Designed to support stronger power delivery in suitable performance configurations.
• Supports Throttle Responsiveness: Fabspeed advertises improved throttle response.
• Reduces Exhaust System Weight: Fabspeed lists a weight reduction of approximately 25 lb.
• Uses Corrosion-Resistant Stainless Steel: T304L construction offers durability under high exhaust temperatures.
• Maintains Smooth Pipe Geometry: CNC mandrel bending helps preserve consistent internal tubing dimensions.
• Integrates with Compatible Fabspeed Systems: Designed for selected existing Maxflo and Supersport X-Pipe exhaust configurations.
• Supports Motorsport Preparation: Provides a catalyst-free configuration for vehicles used in permitted competition or closed-course environments.
• Allows Modular Exhaust Configuration: Enables compatible Fabspeed exhaust systems to use either the appropriate catalytic converter sections or the bypass configuration.

Symptoms Of Wear Or Failure:
The Fabspeed Cat Bypass Pipes are primarily a motorsport performance modification, not a standard maintenance replacement.

However, owners may be considering them while inspecting deteriorated exhaust components or preparing a dedicated track vehicle.

1. Corroded Exhaust Pipework

Exposure to moisture, heat and environmental contamination can cause corrosion around exhaust pipes, joints and flanges.

Advanced corrosion may weaken the affected sections and lead to leakage.

2. Cracked Exhaust Welds

Repeated heating and cooling, vibration or mechanical stress can contribute to cracks around welded joints.

Possible signs include exhaust blowing noises and visible soot deposits.

3. Exhaust Leaks

Damaged flanges, failed gaskets or cracked pipework can allow exhaust gases to escape before reaching the tailpipes.

Exhaust leaks may create hissing, blowing or ticking sounds.

4. Restricted Catalytic Converters

A damaged or internally deteriorated catalyst may become partially blocked.

A significant restriction can increase exhaust backpressure and reduce engine performance.

5. Loose Catalytic Converter Substrate

Damage within a catalytic converter may cause internal rattling or metallic vibration.

These noises can sometimes change with engine speed or load.

6. Reduced Engine Performance

Excessive exhaust restriction may contribute to reduced power or sluggish acceleration.

However, poor performance can also be caused by ignition faults, boost leaks, faulty sensors or turbocharger problems.

7. Unusual Exhaust Temperatures

Severe restrictions or engine combustion faults may contribute to abnormal exhaust temperatures.

The cause should be diagnosed before any performance modification is made.

8. Damaged Exhaust Flanges

Corroded or distorted flanges may prevent exhaust sections from sealing correctly.

9. Deteriorated Mounting Hardware

Loose or damaged exhaust fasteners can cause movement, rattling and leaks.

10. Unwanted Exhaust Vibration

Poor alignment, damaged supports or cracked components may produce vibration or metallic contact with the surrounding bodywork.

11. Exhaust-Related Diagnostic Faults

Catalytic converter efficiency faults or exhaust sensor problems may trigger an engine warning light.

The underlying cause requires proper diagnosis rather than simply removing the converter.

12. Visible Impact Damage

Exhaust pipes or catalytic converter housings may be damaged by road debris, contact with obstacles or incorrect lifting procedures.

Why Replacement / Upgrading Matters:

• The exhaust system is an important part of the Porsche 996 Turbo's engine operation.
• Exhaust gases drive the turbochargers before passing through the downstream exhaust components.
• The design of the exhaust system can influence gas flow, pressure and the sound characteristics of the vehicle.
• For a dedicated competition or closed-track Porsche 996 Turbo, Fabspeed Cat Bypass Pipes provide a way to configure an existing Fabspeed exhaust for reduced downstream restriction.

NOTE: In the United Kingdom, sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001. They are not MOT compliant and cannot be used on public roads. These components are intended solely for race and track use.

For vehicles manufactured before 1st March 2001, a non-type approved sports catalytic converter may be fitted, provided it offers comparable performance to the original and the vehicle continues to meet the applicable emissions standards for its age. The vehicle must still pass an MOT test.

If you are located outside the UK, please check your local laws and regulations to ensure compliance.

Symptoms Of Wear Or Failure:
The Fabspeed Maxflo Performance Exhaust System is primarily a performance upgrade rather than a routine maintenance replacement.

However, owners may consider replacing the original exhaust when components show signs of deterioration, corrosion or mechanical damage.

Common symptoms include:

• The factory exhaust is exposed to moisture, road salt and repeated heating and cooling.
• Over time, corrosion can develop around mufflers, pipes, flanges and mounting points.
• Advanced corrosion may weaken the exhaust assembly and cause leaks.
• Cracks, damaged joints or deteriorated gaskets may allow exhaust gases to escape before reaching the intended outlet.
• Common signs include blowing or hissing noises, soot around connections and unusual exhaust smells.
• Internal components within an ageing muffler may loosen or become damaged.
• This can cause metallic rattling, unwanted vibration and changes in exhaust sound.
• A severely restricted exhaust or damaged catalytic converter may increase backpressure and affect engine performance.
• The vehicle may feel less responsive or deliver reduced power under load.
• However, reduced performance can also result from boost leaks, ignition faults, fuel delivery problems or turbocharger issues.
• Ageing or damaged catalytic converters can develop internal restrictions or physical deterioration.
• Possible signs include reduced power, unusual exhaust noises and elevated exhaust temperatures.
• Any suspected catalyst fault should be professionally diagnosed.
• Loose mounting brackets, deteriorated exhaust supports or damaged internal components may cause unwanted rattling.
• These noises may become more noticeable during acceleration or over uneven roads.
• Rust and repeated heat exposure can weaken exhaust connections.
• Damaged flange surfaces or fixings may prevent the system from sealing correctly.
• Impact damage, crushed pipework, cracked welds or distorted mounting points may compromise the condition of the original system.
• An exhaust leak may allow fumes to escape near the engine compartment or vehicle body.
• Exhaust gases can contain dangerous carbon monoxide, so suspected leaks should be investigated promptly.
• Certain exhaust or catalytic converter faults may trigger diagnostic trouble codes or an engine warning light.
• However, warning lights can have many causes. Replacing the exhaust should not be treated as a guaranteed solution without diagnosis.
• Excessive downstream exhaust restriction may influence turbocharger operation.
• However, slow boost response can also result from boost leaks, faulty control valves, wastegate problems or turbocharger deterioration.
• An unexpectedly loud or harsh exhaust sound may indicate a leak or failed muffler rather than normal performance exhaust behaviour.

Why Replacement / Upgrading Matters:

• Upgrading the exhaust system of the Porsche 996 Turbo can improve its sound, performance character and overall driving experience.
• The factory Porsche 996 Turbo exhaust was developed to balance power delivery, emissions control, sound suppression and everyday refinement.

Fabspeed Muffler Bypass Pipes.

The Fabspeed Muffler Bypass Pipes are a performance-focused exhaust upgrade designed for compatible Porsche 996 Turbo, X50 and GT2 applications.

Fits:

• Porsche 996 TURBO 2000-05
• Porsche 996 GT2 2001-05  

These straight-through pipes replace the Fabspeed Maxflo rear mufflers, creating a much more direct exhaust path from the Fabspeed Sport Catalytic Converters to the exhaust tips. Removing the mufflers substantially increases exhaust volume and gives the 996 Turbo a raw, aggressive motorsport-inspired sound.

The system also removes a considerable amount of rear exhaust weight. Fabspeed states that this configuration saves approximately 50 lb compared with the standard 996 Turbo exhaust system.

These bypass pipes are specifically designed as part of the Fabspeed modular exhaust system. Existing Fabspeed Sport Catalytic Converters are required, and the pipes will not directly fit the original Porsche exhaust or other aftermarket 996 Turbo systems.

What This Product Does:
A conventional rear muffler reduces exhaust noise by forcing exhaust gases through internal chambers, perforated tubes or sound-absorbing structures.

The Fabspeed Muffler Bypass Pipes eliminate the rear mufflers and provide a much more direct path for exhaust gases to travel towards the tailpipes.

Their primary functions and benefits include:

• Eliminating the Fabspeed Maxflo rear mufflers
• Creating a freer and more direct exhaust route
• Producing a considerably louder and more aggressive exhaust note
• Reducing rear exhaust system weight
• Allowing reuse of compatible factory, aftermarket or Fabspeed exhaust tips
• Providing a motorsport-inspired exhaust character
• Allowing compatible Fabspeed systems to be converted between muffled and bypass configurations

Fabspeed specifically designed the system to be interchangeable, allowing owners with the required Fabspeed components to change between a muffler and muffler-bypass arrangement.

Symptoms Of Wear Or Failure:
Exhaust bypass pipes contain fewer internal components than conventional mufflers, but they are still exposed to extreme heat, vibration, moisture and road contamination.

Signs that the bypass pipes or their connections may require attention include:

• Cracks around welds or pipe joints
• Exhaust blowing or hissing sounds
• Black soot around leaking connections
• Loose clamps or mounting hardware
• Excessive movement or vibration
• Metallic rattling from loose mounting points
• Visible corrosion or surface deterioration
• Dents or impact damage to the pipework
• Exhaust tips becoming incorrectly aligned
• Exhaust fumes escaping from joints before the tailpipes
• Unusual changes in exhaust sound
• Pipes contacting surrounding bodywork or heat shields

If the vehicle is still fitted with its original mufflers, deterioration may instead appear as rattling internal components, corrosion, cracking, exhaust leaks or damage to the muffler casing.

Why Replacement / Upgrading Matters:

• A damaged exhaust pipe or leaking connection can allow hot exhaust gases to escape before reaching the intended outlets. This can create unwanted noise, soot deposits and additional heat around nearby components.
• Cracked or poorly supported exhaust components can also move excessively and place additional load on mounting brackets, joints and surrounding parts.
• Where the existing Fabspeed Maxflo system is in good condition, fitting the Muffler Bypass Pipes is primarily a performance-sound and weight-reduction upgrade rather than a necessary repair. The bypass configuration removes the rear mufflers and gives the 996 Turbo a significantly more aggressive exhaust character.
• For owners using their vehicle for performance driving or seeking a more dramatic exhaust note, the reduced restriction and considerable weight saving can make the bypass configuration particularly attractive.
• If replacing worn or damaged exhaust components, restoring secure, correctly aligned pipework also ensures that exhaust gases are directed safely to the rear of the vehicle.

Fabspeed RACE Muffler Bypass Exhaust System, Includes Catbypass.

The Fabspeed Muffler Bypass Exhaust System is a high-performance exhaust upgrade designed for the 2000–2005 Porsche 996 Turbo.

Fits:

• Porsche 996 TURBO 2000-05

Developed for drivers looking for maximum exhaust character and reduced restriction, the system replaces the restrictive factory muffler arrangement with a much freer-flowing bypass design. The result is a significantly louder, more aggressive exhaust note together with improved exhaust flow, sharper throttle response and reduced rear-end weight.

Fabspeed offers the system in two configurations. The Race configuration uses catalyst-bypass pipes for maximum flow. Fabspeed notes that emissions-related configurations may be restricted to closed-course or off-road use depending on local legislation, so applicable regulations should be checked before installation.

Manufactured from 14–16 gauge CNC mandrel-bent T304L stainless steel, the system is designed to provide excellent heat resistance, corrosion resistance and long-term durability. Fabspeed also states that the system removes approximately 45 lb (20 kg) from the rear of the vehicle compared with the factory arrangement.

What This Product Does:
The exhaust system carries combustion gases away from the turbochargers and engine. Factory mufflers are designed to control exhaust volume, but they also introduce resistance into the exhaust path.

The Fabspeed Muffler Bypass system removes much of this restriction by providing a more direct exhaust route.

Its key functions and benefits include:

• Reducing exhaust backpressure and restriction
• Improving exhaust gas flow
• Helping the turbocharged engine breathe more freely
• Improving throttle response
• Supporting increased horsepower and torque
• Producing a much louder and more aggressive exhaust note
• Reducing weight at the rear of the vehicle
• Replacing ageing factory exhaust components with stainless-steel alternatives

Fabspeed publishes gains of approximately 37 hp and 42 lb-ft of torque for this system, although actual results can vary depending on vehicle condition, modifications and configuration.

This is one of Fabspeed's more aggressive exhaust options and is particularly suited to owners prioritising performance and exhaust sound rather than factory-level refinement.

Symptoms Of Wear Or Failure:
Porsche 996 Turbo models are now more than two decades old, meaning original exhaust components may have experienced thousands of heat cycles along with moisture, road salt and vibration.

Common signs of exhaust deterioration include:

• Rust or corrosion on exhaust pipes or silencers
• Cracks around welds and joints
• Exhaust leaks
• Blowing, ticking or hissing noises
• Rattling from deteriorated muffler internals
• Loose exhaust components or mounting points
• Increased exhaust noise in unexpected areas
• Exhaust fumes around the rear of the vehicle
• Soot deposits around leaking joints
• Reduced engine performance
• Slower or less responsive turbo performance
• Increased exhaust restriction
• Check Engine Light associated with catalyst efficiency
• Metallic rattling from damaged catalytic converter material
• Sulphur-like or unusual exhaust smells
• Visible damage to exhaust pipework

A deteriorated or internally damaged catalytic converter can also restrict exhaust flow. This may contribute to reduced performance and increased exhaust temperatures.

Why Replacement / Upgrading Matters:

• A leaking, corroded or restricted exhaust system can affect both performance and reliability.
• On a turbocharged engine such as the Porsche 996 Turbo, efficient exhaust flow downstream of the turbochargers is particularly important. Excessive restriction can work against efficient gas evacuation and may negatively affect throttle response and overall performance.
• Exhaust leaks can also produce unwanted noise and allow hot exhaust gases to escape close to surrounding components. Severe corrosion can weaken pipework, joints and mounting points until components become loose or fail completely.
• A damaged or partially blocked catalytic converter can create additional exhaust restriction and potentially increase thermal stress within the exhaust system.
• Replacing deteriorated factory components with the Fabspeed Muffler Bypass system restores a secure exhaust path while substantially reducing restriction and weight. For owners seeking a performance-focused setup, it also provides a much more pronounced turbocharged exhaust sound.

Fabspeed RACE Supersport 70mm X-Pipe Exhaust System, Includes Catbypass.
The Fabspeed Supersport 70mm X-Pipe Exhaust System is a high-performance exhaust upgrade designed for the 2000–2005 Porsche 996 Turbo and Turbo S.

Fits:

Running from the turbocharger outlets through to the exhaust tips, the system replaces restrictive sections of the original exhaust with a freer-flowing 70mm X-pipe configuration. The design is intended to improve exhaust gas flow, reduce restriction and give the 996 Turbo a considerably more aggressive exhaust note.

The Race application configuration using catalyst-bypass pipes with oxygen-sensor locations matching the factory arrangement; this version is intended for off-road or track use only.

Constructed from 14–16 gauge CNC mandrel-bent T304L stainless steel, the system is designed for durability, corrosion resistance and smooth internal exhaust flow. Fabspeed states gains of approximately 32 wheel horsepower and 37 ft-lb of torque, depending on vehicle condition and configuration.

What This Product Does:
The exhaust system carries combustion gases away from the turbochargers and engine while controlling exhaust flow, noise and, where catalytic converters are fitted, emissions.

On a turbocharged engine, excessive exhaust restriction after the turbochargers can work against efficient gas evacuation. The Fabspeed 70mm system uses larger, smoother-flowing pipework and an X-pipe layout to reduce restriction and improve exhaust flow.

Potential benefits include:

• Improved exhaust gas flow
• Reduced post-turbo exhaust restriction
• Increased horsepower and torque
• Sharper engine response
• A deeper and more aggressive exhaust sound
• Reduced weight compared with the factory system
• Improved durability through stainless-steel construction

The Supersport system is positioned between Fabspeed's quieter Maxflo system and its louder Muffler Bypass system, providing a more aggressive exhaust character without being its most extreme exhaust option.

Symptoms Of Wear Or Failure:
The original exhaust system on a 996 Turbo is now potentially more than two decades old, and heat cycles, condensation, road salt and vibration can gradually deteriorate exhaust components.

Common symptoms that may indicate exhaust deterioration include:

• Rust or corrosion on exhaust pipes and silencers
• Cracks around welds, joints or mounting points
• Exhaust gas leaks
• A blowing, ticking or hissing sound
• Increased or unusual exhaust noise
• Rattling from loose internal components or heat shields
• Exhaust fumes around the rear of the vehicle
• Reduced engine performance or throttle response
• Increased turbo lag where exhaust restriction becomes excessive
• Visible damage or deformation to exhaust pipework
• Failed or deteriorating catalytic converters
• Check Engine Light associated with catalyst efficiency or oxygen-sensor faults
• Sulphur or unusual exhaust smells
• Restricted exhaust flow caused by a damaged or partially blocked catalytic converter

Catalytic converters can deteriorate internally with age and repeated heat cycling. A damaged catalyst substrate may break apart, rattle or restrict exhaust flow, potentially reducing performance.

Why Replacement / Upgrading Matters:

• A damaged or heavily deteriorated exhaust system can affect more than sound and appearance. Exhaust leaks can allow gases to escape before reaching the intended outlets, while damaged or restricted catalytic converters can interfere with exhaust flow and reduce engine performance.
• This is particularly important on a turbocharged Porsche 996, where efficient exhaust flow downstream of the turbochargers plays an important role in overall engine and turbocharger performance.
• Replacing an ageing or restrictive exhaust system can help restore secure, leak-free exhaust operation while improving flow and durability. For owners seeking a performance upgrade, the Fabspeed Supersport system also provides larger-diameter pipework and a freer-flowing X-pipe configuration designed to take greater advantage of the 996 Turbo's performance potential.
• The stainless-steel construction also offers improved resistance to corrosion compared with an ageing original exhaust, making the system suitable both as a replacement for deteriorated components and as a performance-oriented upgrade.

Key Features:

• Fits Porsche 996 Turbo and Turbo S models from 2000–2005
• 70mm Supersport X-pipe exhaust design
• Runs from the turbo outlets to the exhaust tips
• Race version available with catalyst-bypass pipes for off-road/track use 
• Claimed increase of approximately 32 whp and 37 ft-lb of torque
• 14–16 gauge CNC mandrel-bent T304L stainless-steel construction
• Designed to improve exhaust flow and sound
• Direct bolt-on installation
• More aggressive sound than Fabspeed's Maxflo system

Fabspeed Sport Headers.

The Fabspeed Sport Headers are a high-performance direct replacement for the factory exhaust manifolds on 2000–2005 Porsche 996 Turbo models.

Fits:

• Porsche 996 TURBO 2000-05

Designed to improve exhaust gas flow from the engine to the turbochargers, these headers use equal-length, one-piece CNC mandrel-bent primary tubes and a 3-into-1 high-velocity merge collector. This layout is engineered to provide smoother, less restrictive exhaust flow compared with the original manifold arrangement.

Manufactured from high-quality 14–16 gauge T304L stainless steel, the headers offer excellent resistance to corrosion and repeated high-temperature exhaust cycles. They are designed as a direct replacement for the factory headers and can be combined with the standard exhaust or other compatible performance exhaust upgrades.

Fabspeed reports gains of approximately 12 wheel horsepower and 14 ft-lb of torque, together with a weight saving of approximately 3 lb. Actual performance gains can vary depending on vehicle condition, modifications and operating conditions.

What This Product Does:
The exhaust headers collect exhaust gases leaving each cylinder and direct them towards the turbochargers.

On a turbocharged engine, efficient exhaust flow before the turbocharger is particularly important because the energy contained in the exhaust gases is used to drive the turbine wheel and generate boost.

The Fabspeed Sport Headers are designed to improve this part of the exhaust path through equal-length primary tubes and a high-flow merge collector.

Potential benefits include:

• Improved exhaust gas flow
• Reduced restriction compared with restrictive or deteriorated factory manifolds
• More efficient delivery of exhaust gases to the turbochargers
• Improved throttle and engine response
• Support for increased horsepower and torque
• Smoother merging of exhaust pulses
• Reduced weight compared with the original headers
• Improved corrosion resistance through stainless-steel construction

Fabspeed's equal-length primary tube design is intended to maintain uninterrupted flow into the 3-into-1 collectors before the exhaust gases reach the turbochargers.

Symptoms Of Wear Or Failure:
The factory headers on a Porsche 996 Turbo are exposed to extremely high exhaust temperatures, repeated heat cycling and vibration. As vehicles age, manifolds, welds, flanges and associated hardware can deteriorate.

Common symptoms of header or exhaust manifold problems include:

• Ticking or tapping noises when the engine is cold
• Blowing or hissing noises from the exhaust manifold area
• Exhaust leaks around the cylinder-head flanges
• Black soot deposits around leaking joints
• Cracks in the manifold or around welded areas
• Warped or damaged mounting flanges
• Broken or corroded mounting hardware
• Exhaust fumes or unusual smells around the rear of the vehicle
• Increased exhaust noise from the engine area
• Reduced engine response
• Poor or inconsistent turbo response
• Loss of performance where a significant exhaust leak is present
• Increased heat around neighbouring engine components

Some of these symptoms can also result from failed gaskets, loose mounting hardware or other exhaust components, so the complete manifold assembly should be inspected before replacement.

Why Replacement Matters:

• The exhaust headers operate in one of the hottest and most demanding areas of the engine. A crack, warped flange or leaking connection can allow exhaust gases to escape before reaching the turbocharger.
• On a turbocharged engine, an exhaust leak upstream of the turbocharger can reduce the amount of exhaust energy reaching the turbine. Depending on the severity of the leak, this may contribute to reduced turbo response and poorer overall engine performance.
• Escaping exhaust gases can also expose surrounding components to excessive heat and create unwanted noise.
• Replacing damaged or restrictive factory headers restores a properly sealed exhaust path between the cylinder heads and turbochargers. Upgrading to a freer-flowing design can additionally improve exhaust flow and support other performance modifications.
• The Fabspeed Sport Headers provide a durable stainless-steel alternative to ageing factory manifolds while their equal-length layout and merge collectors are designed specifically to improve exhaust efficiency.

Ideal for Porsche 996 Turbo enthusiasts seeking improved exhaust sound, reduced weight and enhanced performance characteristics, the Fabspeed Maxflo Performance Exhaust System combines durable construction with performance-focused engineering.

What This Product Does:
The Fabspeed Maxflo Performance Exhaust System replaces selected original exhaust components with a freer-flowing stainless steel arrangement.

On the Porsche 996 Turbo, exhaust gases pass through the turbochargers before travelling through the downstream exhaust system.

Reducing restriction after the turbochargers can help improve exhaust gas evacuation and create more favourable conditions for turbocharger operation.

Its key functions and benefits include:

• Improved Exhaust Flow: Uses performance-oriented pipework and mufflers to reduce restrictions within the downstream exhaust system.
• Reduced Exhaust Backpressure: High-flow components help limit unnecessary resistance to exhaust gases leaving the turbochargers.
• Enhanced Engine Performance: Fabspeed advertises gains of up to 27 hp and 32 lb-ft of torque.
• Improved Throttle Response: The system is designed to provide more responsive power delivery.
• Enhanced Turbocharger Sound: Allows more of the characteristic twin-turbocharged engine sound to be heard.
• Sportier Exhaust Note: Produces a deeper, more pronounced exhaust sound than the original factory system.
• Balanced Sound Character: The Maxflo design is intended to provide a sporty sound without the extreme volume of a racing exhaust.
• High-Flow Catalytic Conversion: Incorporates 200-cell HJS German sport catalytic converters.
• Reduced Vehicle Weight: Fabspeed advertises a saving of approximately 25 lb (11.3 kg).
• Durable Stainless Steel Construction: T304L stainless steel provides corrosion resistance and thermal durability.
• Customisable Exhaust Appearance: Offers Deluxe X-50 Style Tips or reuse of compatible original Porsche tips.
• Direct Bolt-On Installation: Designed to replace the original exhaust assembly using compatible factory mounting locations.

Symptoms Of Wear Or Failure:
The Fabspeed Maxflo Performance Exhaust System is primarily a performance upgrade rather than a routine maintenance replacement.

However, owners may consider replacing the original exhaust when components show signs of deterioration, corrosion or mechanical damage.

Common symptoms include:

• The factory exhaust is exposed to moisture, road salt and repeated heating and cooling.
• Over time, corrosion can develop around mufflers, pipes, flanges and mounting points.
• Advanced corrosion may weaken the exhaust assembly and cause leaks.
• Cracks, damaged joints or deteriorated gaskets may allow exhaust gases to escape before reaching the intended outlet.
• Common signs include blowing or hissing noises, soot around connections and unusual exhaust smells.
• Internal components within an ageing muffler may loosen or become damaged.
• This can cause metallic rattling, unwanted vibration and changes in exhaust sound.
• A severely restricted exhaust or damaged catalytic converter may increase backpressure and affect engine performance.
• The vehicle may feel less responsive or deliver reduced power under load.
• However, reduced performance can also result from boost leaks, ignition faults, fuel delivery problems or turbocharger issues.
• Ageing or damaged catalytic converters can develop internal restrictions or physical deterioration.
• Possible signs include reduced power, unusual exhaust noises and elevated exhaust temperatures.
• Any suspected catalyst fault should be professionally diagnosed.
• Loose mounting brackets, deteriorated exhaust supports or damaged internal components may cause unwanted rattling.
• These noises may become more noticeable during acceleration or over uneven roads.
• Rust and repeated heat exposure can weaken exhaust connections.
• Damaged flange surfaces or fixings may prevent the system from sealing correctly.
• Impact damage, crushed pipework, cracked welds or distorted mounting points may compromise the condition of the original system.
• An exhaust leak may allow fumes to escape near the engine compartment or vehicle body.
• Exhaust gases can contain dangerous carbon monoxide, so suspected leaks should be investigated promptly.
• Certain exhaust or catalytic converter faults may trigger diagnostic trouble codes or an engine warning light.
• However, warning lights can have many causes. Replacing the exhaust should not be treated as a guaranteed solution without diagnosis.
• Excessive downstream exhaust restriction may influence turbocharger operation.
• However, slow boost response can also result from boost leaks, faulty control valves, wastegate problems or turbocharger deterioration.
• An unexpectedly loud or harsh exhaust sound may indicate a leak or failed muffler rather than normal performance exhaust behaviour.

Why Replacement / Upgrading Matters:

• Upgrading the exhaust system of the Porsche 996 Turbo can improve its sound, performance character and overall driving experience.
• The factory Porsche 996 Turbo exhaust was developed to balance power delivery, emissions control, sound suppression and everyday refinement.
• For owners seeking a more engaging exhaust note and freer-flowing system, the Fabspeed Maxflo exhaust provides a performance-oriented alternative.

Fabspeed STREET Supersport 70mm X-Pipe Exhaust System, Includes Sport Cats.
The Fabspeed Supersport 70mm X-Pipe Exhaust System is a high-performance exhaust upgrade designed for the 2000–2005 Porsche 996 Turbo and Turbo S.

Fits:

Running from the turbocharger outlets through to the exhaust tips, the system replaces restrictive sections of the original exhaust with a freer-flowing 70mm X-pipe configuration. The design is intended to improve exhaust gas flow, reduce restriction and give the 996 Turbo a considerably more aggressive exhaust note.

The Street application incorporates 200-cell HJS Sport catalytic converters, combining increased exhaust flow with catalytic emissions control.

Constructed from 14–16 gauge CNC mandrel-bent T304L stainless steel, the system is designed for durability, corrosion resistance and smooth internal exhaust flow. Fabspeed states gains of approximately 32 wheel horsepower and 37 ft-lb of torque, depending on vehicle condition and configuration.

What This Product Does:
The exhaust system carries combustion gases away from the turbochargers and engine while controlling exhaust flow, noise and, where catalytic converters are fitted, emissions.

On a turbocharged engine, excessive exhaust restriction after the turbochargers can work against efficient gas evacuation. The Fabspeed 70mm system uses larger, smoother-flowing pipework and an X-pipe layout to reduce restriction and improve exhaust flow.

Potential benefits include:

• Improved exhaust gas flow
• Reduced post-turbo exhaust restriction
• Increased horsepower and torque
• Sharper engine response
• A deeper and more aggressive exhaust sound
• Reduced weight compared with the factory system
• Improved durability through stainless-steel construction

The Supersport system is positioned between Fabspeed's quieter Maxflo system and its louder Muffler Bypass system, providing a more aggressive exhaust character without being its most extreme exhaust option.

Symptoms Of Wear Or Failure:
The original exhaust system on a 996 Turbo is now potentially more than two decades old, and heat cycles, condensation, road salt and vibration can gradually deteriorate exhaust components.

Common symptoms that may indicate exhaust deterioration include:

• Rust or corrosion on exhaust pipes and silencers
• Cracks around welds, joints or mounting points
• Exhaust gas leaks
• A blowing, ticking or hissing sound
• Increased or unusual exhaust noise
• Rattling from loose internal components or heat shields
• Exhaust fumes around the rear of the vehicle
• Reduced engine performance or throttle response
• Increased turbo lag where exhaust restriction becomes excessive
• Visible damage or deformation to exhaust pipework
• Failed or deteriorating catalytic converters
• Check Engine Light associated with catalyst efficiency or oxygen-sensor faults
• Sulphur or unusual exhaust smells
• Restricted exhaust flow caused by a damaged or partially blocked catalytic converter

Catalytic converters can deteriorate internally with age and repeated heat cycling. A damaged catalyst substrate may break apart, rattle or restrict exhaust flow, potentially reducing performance.

Why Replacement / Upgrading Matters:

• A damaged or heavily deteriorated exhaust system can affect more than sound and appearance. Exhaust leaks can allow gases to escape before reaching the intended outlets, while damaged or restricted catalytic converters can interfere with exhaust flow and reduce engine performance.
• This is particularly important on a turbocharged Porsche 996, where efficient exhaust flow downstream of the turbochargers plays an important role in overall engine and turbocharger performance.
• Replacing an ageing or restrictive exhaust system can help restore secure, leak-free exhaust operation while improving flow and durability. For owners seeking a performance upgrade, the Fabspeed Supersport system also provides larger-diameter pipework and a freer-flowing X-pipe configuration designed to take greater advantage of the 996 Turbo's performance potential.
• The stainless-steel construction also offers improved resistance to corrosion compared with an ageing original exhaust, making the system suitable both as a replacement for deteriorated components and as a performance-oriented upgrade.

Key Features:

• Fits Porsche 996 Turbo and Turbo S models from 2000–2005
• 70mm Supersport X-pipe exhaust design
• Runs from the turbo outlets to the exhaust tips
• Street version features 200-cell HJS Sport catalytic converters
• Claimed increase of approximately 32 whp and 37 ft-lb of torque
• 14–16 gauge CNC mandrel-bent T304L stainless-steel construction
• Designed to improve exhaust flow and sound
• Direct bolt-on installation
• More aggressive sound than Fabspeed's Maxflo system
