A Quick Look at Fabspeed
Fabspeed information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.
Choosing the Right Fit for Your Porsche
Where Fabspeed is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.
- Typical reasons people replace these parts include upgrading tired or corroded factory exhaust components, tailoring sound and response for fast-road or track use, and supporting wider tuning packages.
- Common symptoms that lead owners to inspect or change related parts include exhaust leaks, rattles, drone, heat-related fatigue, and loss of performance that may also be linked to boost or vacuum issues.
- After installation, it is sensible to refresh mounts and hardware where worn, and to carry out a careful check for leaks once everything has heat-cycled.
- Consider whether supporting ECU mapping or health checks are appropriate for your Porsche, depending on how extensive your hardware changes are.
Browse by Category
If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.
Engine Tuning — Engine tuning parts and upgrades for Porsche are used to improve drivability, throttle response and power, or to support changes such as intake, exhaust, or forced induction. They are typically chosen once the engine is in good health, as tuning cannot compensate for underlying mechanical faults.
- Before any significant tuning work, check overall engine condition, including compression or leak-down where appropriate, fuel system health, sensor data, and that there are no boost or vacuum leaks.
- Avoid using calibration changes to hide rough running or misfires, as the mechanical root cause still needs to be addressed.
Air Filters — Air filters for Porsche protect the engine from dirt while maintaining the airflow that correct fuelling and performance depend on. Owners often replace or upgrade filters to restore airflow, support tuning work, or improve serviceability while keeping good filtration.
- Service intervals depend on use: dusty environments or frequent track days may justify more frequent inspection and cleaning or replacement.
- If using oiled performance filters, follow the manufacturer’s oiling instructions carefully to avoid contaminating sensitive airflow sensors.
Air Induction Kits — Induction kits for Porsche replace or re-route parts of the intake system to change airflow, response and sound. They are usually part of a wider tuning package and are selected to balance intake temperatures, flow and sensor stability.
- When fitting an induction kit, ensure joints and connections are well sealed to prevent unmetered air entering the engine or causing drivability issues.
- Positioning and heat management are important: shielding from hot engine-bay air helps keep intake temperatures, and therefore performance, more consistent.
Exhausts — Exhaust upgrades for Porsche are commonly chosen to replace corroded or leaking factory systems, refine the car’s sound, reduce weight or improve gas flow as part of a tuning package. The right choice depends on how the car is used and the balance you want between sound, comfort and responsiveness.
- When planning an exhaust change, consider the complete system, including catalytic converters, to keep within your local emissions and noise requirements.
- Replacing aged gaskets, clamps, mounts and rusted fixings at the same time as the exhaust usually improves fitment and reduces the chance of future leaks or rattles.
All Silencers / Mufflers — This category covers a range of Porsche silencer and muffler layouts, from standard-style replacements to sport and valved options. Selection is usually guided by corrosion or damage to existing parts, unwanted noise or drone, or a desire to change the exhaust character while staying within comfort and usage needs.
- To narrow down the correct layout, compare inlet and outlet positions, hanger locations and pipe diameters on your current system against the product details.
- When choosing between standard, sport or switchable systems, think about typical journeys and cabin noise tolerance so you end up with a sound level that suits day-to-day use.

The Fabspeed Deluxe Quad Style Exhaust Tips are a premium bolt-on replacement and styling upgrade for the 2008–2010 Porsche 957 Cayenne S.
Fits:
- Porsche 957 Cayenne S 4.8L 2008-10
Designed to fit the original factory exhaust as well as most aftermarket exhaust systems with removable tips, these quad-style outlets give the Cayenne S a more aggressive, performance-inspired rear appearance without requiring replacement of the complete exhaust system.
Manufactured from high-quality 14–16 gauge T304 stainless steel, the tips are engineered to withstand exhaust heat, moisture and everyday road exposure. Installation is designed to be a straightforward bolt-on process.
Please Note: these exhaust tips do not fit Cayenne GTS models or Cayenne S vehicles equipped with the Porsche Sport Exhaust (PSE) option.
What This Product Does:
- Exhaust tips form the visible end section of the vehicle's exhaust system, providing a finished outlet for exhaust gases while contributing significantly to the appearance of the rear of the vehicle.
- The Fabspeed Deluxe Quad Style Tips replace the standard removable exhaust outlets with a distinctive four-tip arrangement. They allow owners to refresh or enhance the appearance of the Cayenne S without replacing the silencers or complete exhaust system.
- The upgrade is primarily intended to improve appearance, durability and exhaust outlet condition rather than provide a significant increase in engine power.
Symptoms Of Wear Or Failure:
Exhaust tips are continually exposed to extreme temperature changes, moisture, condensation, exhaust deposits, road dirt and winter salt. Over time, ageing exhaust tips may show signs such as:
- Rust, corrosion or surface pitting
- Heavy staining or permanent discolouration
- Flaking, peeling or deterioration of the original finish
- Dents, scratches or deformation
- Loose or misaligned exhaust tips
- Rattling or vibration from worn mounting points
- Cracks around welds, joints or fixing areas
- Excessive soot around the tip-to-exhaust connection
- Tips sitting unevenly or making contact with the rear bumper
- A generally tired or deteriorated appearance that cannot be restored through cleaning
If corrosion becomes severe, the metal or mounting areas may weaken enough for the tip to become insecure.
Why Replacement / Upgrading Matters:
- Replacing worn or damaged exhaust tips helps restore the finished appearance of the Cayenne S while ensuring that the exhaust outlets remain securely mounted and correctly aligned.
- Loose, damaged or badly corroded tips can cause vibration and rattling and, in some cases, may move sufficiently to contact surrounding bumper or trim components. Advanced corrosion can also weaken the mounting area and increase the possibility of the exhaust tip becoming detached.
- For vehicles where the original outlets are cosmetically deteriorated but the remainder of the exhaust system remains serviceable, replacement tips provide a practical alternative to changing the complete exhaust assembly.
- The Fabspeed T304 stainless-steel construction also provides a durable replacement for ageing original tips while giving the Porsche Cayenne S a more distinctive quad-outlet appearance.

The Fabspeed Deluxe Quad Style Exhaust Tips are a premium replacement and visual upgrade for the 2008–2010 Porsche 957 Cayenne Turbo and Turbo S. Designed to bolt onto both factory and compatible aftermarket exhaust systems, the quad-tip arrangement gives the rear of the Cayenne a more purposeful, performance-inspired appearance while replacing ageing, damaged or corroded original exhaust outlets.
Fits:
- Porsche 957 Cayenne Turbo / Turbo S 4.8L 2008-10
Manufactured from heavy-duty T304 stainless steel, these tips are designed to withstand the heat, moisture and corrosive exhaust environment found at the rear of the vehicle. Their polished finish provides a clean, high-quality appearance that complements the Cayenne Turbo's performance character.
What This Product Does:
- Exhaust tips form the visible termination of the exhaust system. They direct exhaust gases away from the rear bumper while providing a finished appearance to the tailpipe outlets.
- The Fabspeed Deluxe Quad Style Tips replace the existing outlets with a larger, sportier quad-tip design. Their primary benefits are improved appearance, durable stainless-steel construction and restoration of exhaust outlets that have become worn or damaged.
- Unlike a complete performance exhaust, replacing the tips alone is principally a cosmetic and durability upgrade rather than a significant power modification.
Symptoms Of Wear Or Failure:
Exhaust tips are constantly exposed to heat, exhaust gases, condensation, road salt, dirt and moisture.
Over time, the original tips may develop:
- Heavy corrosion, rust or surface pitting
- Permanent staining or excessive discolouration
- Peeling, damaged or deteriorated exterior finishes
- Dents or deformation around the exhaust outlets
- Loose or misaligned tips
- Rattling or vibration from damaged mounting points
- Cracks around joints, welds or attachment areas
- Excessive soot around the connection between the tip and exhaust pipe
Severe corrosion or physical damage can eventually weaken the tip sufficiently for it to loosen or detach.
Why Replacement / Upgrading Matters:
- Replacing deteriorated exhaust tips restores the appearance of the rear of the vehicle and ensures that the exhaust outlets remain securely attached and correctly positioned. On a performance model such as the Cayenne Turbo, damaged, heavily corroded or misaligned tips can noticeably detract from the vehicle's overall condition.
- Replacement is particularly worthwhile where corrosion has weakened the original outlets, mounting points have become loose, or previous damage has left the tips distorted. Secure, properly fitted tips also reduce the possibility of rattles, unwanted movement and contact with the rear bumper.
- The Fabspeed stainless-steel replacements provide a durable alternative to ageing factory tips while giving the Cayenne Turbo and Turbo S a distinctive quad-outlet appearance.

Unlike a generic mechanical modification, the calibration is prepared using information about the individual vehicle and its existing modifications.
Custom ECU Calibration:
Fabspeed uses the stock ECU data together with information supplied about the vehicle to develop the tune.
This allows the calibration to account for the vehicle's particular specification and modifications.
Relevant modifications may include:
- Performance exhaust systems
- Sport catalytic converters
- Intake upgrades
- Air filters
- Other compatible performance components
Accurate vehicle information should be supplied so the calibration can be developed for the correct setup.
OBD Handheld Tuning:

What This Product Does:
The package improves the way the Cayenne Turbo's engine draws in air, expels exhaust gases and manages engine performance.
The individual components work together:
- BMC F1 Air Filters improve intake airflow while maintaining filtration.
- 200-Cell HJS Sport Catalytic Converters provide a less restrictive catalyst arrangement than the factory system.
- Secondary Cat Bypass Pipes remove the secondary catalytic converters to further reduce exhaust restriction.
- Maxflo Performance Mufflers improve rear exhaust flow and provide a deeper performance exhaust note.
- Fabspeed ECU Tuning recalibrates the engine-management system to optimise performance for the vehicle and its modifications.
The result is a coordinated performance package rather than a collection of unrelated upgrades.

Rather than replacing a mechanical engine component, XperTune modifies the calibration within the vehicle's engine control unit (ECU) to optimise performance. The tune is developed around the individual vehicle and its modifications, with the aim of increasing horsepower and torque while improving throttle response and overall drivability.
The package includes a MyGenius handheld tuning device, allowing the vehicle's factory ECU data to be read through the OBD-II diagnostic port. This information is supplied to Fabspeed, which creates a custom calibration for the vehicle. The completed tune is then loaded onto the MyGenius device and flashed back to the Cayenne through the OBD-II port.
The original factory calibration can also be restored using the handheld device without removing or mailing the ECU.
What This Product Does:
The ECU controls many of the operating strategies used by the engine.
On a turbocharged performance engine, these can include parameters associated with:
- Boost control
- Ignition timing
- Fuel delivery

This allows Fabspeed to prepare a calibration for the specific setup.
Relevant modifications may include changes to:
- Intake system
- Exhaust system
- Intercooling
- Other compatible performance hardware
Accurate vehicle and modification information should be supplied when requesting the calibration.
MyGenius Handheld Tuner:
The included MyGenius handheld device allows the ECU tuning process to be carried out through the vehicle's OBD-II diagnostic connection.
The normal process is:
- Read the vehicle's stock ECU data through the OBD-II port using MyGenius.
- Connect MyGenius to a Windows computer.
- Supply the factory ECU information and vehicle details to Fabspeed.
- Fabspeed develops the custom tune.
- Load the completed calibration onto the MyGenius device.
- Flash the new calibration to the vehicle through the OBD-II port.
This eliminates the need to remove and mail the ECU for most installations.
Why Upgrading Matters:
The original ECU software does not need to be faulty before installing XperTune.
This product is primarily a performance upgrade.
Reasons for upgrading include:

The Fabspeed Porsche 986 Boxster Primary Sport Catalytic Converters are high-flow replacement catalysts designed for 1997–1999 Porsche 986 Boxster and Boxster S models.
Fits:
- Porsche Boxster 986 2.5L 1997-99
Designed to replace the more restrictive factory catalytic converters, these performance catalysts improve exhaust-gas flow while retaining catalytic converter functionality. The result is a more performance-oriented exhaust path designed to improve throttle response, support increased power potential and enhance the naturally aspirated Porsche flat-six exhaust note.
Fabspeed uses HJS/EMITEC high-flow catalytic converter technology, with the manufacturer specifying a 200 CPSI (cells per square inch) catalyst design. Fabspeed states that these catalysts can flow approximately 90–93% of the volume of a straight pipe in many applications while continuing to provide exhaust-gas treatment.
The converters are designed as a direct bolt-on replacement for the original catalytic converters, making them suitable for use with the factory OEM-style muffler or aftermarket exhaust systems designed to accept the original Porsche catalytic converter arrangement.
What This Product Does:
Catalytic converters form part of the vehicle's exhaust system and are designed to chemically convert harmful exhaust pollutants into less harmful compounds before gases leave the tailpipe.
However, exhaust gases must pass through a catalyst substrate, which creates some resistance to flow.
The Fabspeed Primary Sport Catalytic Converters use a high-flow catalyst design intended to reduce this restriction compared with the original factory catalysts.
Potential benefits include:
- Improved exhaust flow
- Reduced exhaust restriction
- Improved throttle response
- Increased performance potential
- Reduced weight compared with the original catalysts
- Enhanced flat-six exhaust sound
- Retained catalytic converter functionality
200CPSI High-Flow Catalyst Design:
- Catalytic converter density is commonly described in cells per square inch (CPSI).
- A performance-oriented 200 CPSI catalyst provides a relatively open exhaust path while maintaining the large internal surface area required for catalytic exhaust-gas treatment.
- Fabspeed states that its HJS/EMITEC 200 CPSI catalysts can flow approximately 90–93% of a straight pipe in many applications.
- This high-flow construction is designed to provide a balance between exhaust performance and catalyst functionality.
Performance:
Fabspeed states that these Sport Catalytic Converters improve power and throttle response, but the current product listing does not publish specific numerical gains.
The manufacturer currently lists:
Horsepower: TBD
Torque: TBD
Weight: TBD
Specific horsepower, torque or weight-saving figures should therefore not be assumed.

The Fabspeed Porsche 986 Boxster Secondary Cat Bypass Pipes are a competition-focused exhaust upgrade designed to replace the heavy and restrictive factory secondary catalytic converters fitted to 2000–2004 Porsche 986 Boxster and Boxster S models.
Fits:
- Porsche Boxster 986 2.7L 2000-02
- Porsche Boxster S 986 3.2L 2000-02
- Porsche Boxster 986 2.7L 2003-04
- Porsche Boxster S 986 3.2L 2003-04
Manufactured from T304L stainless steel with CNC mandrel-bent tubing, the bypass pipes replace the original secondary catalysts with freer-flowing straight-through exhaust sections. This reduces exhaust restriction and weight while producing a more pronounced flat-six exhaust note and improved throttle response.
Fabspeed reports an increase of 8 wheel horsepower together with a substantial 25 lb (approximately 11.3 kg) weight reduction compared with the factory secondary catalytic converters. These are manufacturer-reported figures, and actual results can vary according to vehicle condition, specification and testing conditions.
These pipes are designed for use with the factory OEM-style muffler and install as a bolt-on replacement without cutting or welding.
What This Product Does:
The factory secondary catalytic converters form part of the Porsche 986 exhaust system and create a degree of restriction as exhaust gases pass through their internal catalyst substrates.
The Fabspeed Secondary Cat Bypass Pipes remove these secondary catalysts and replace them with straight-through exhaust tubing.
This creates a less restrictive path for exhaust gases travelling from the engine toward the rear muffler.
The upgrade is designed to provide:
- Reduced exhaust restriction
- Reduced backpressure
- Improved exhaust flow
- Improved throttle response
- Increased horsepower potential
- Reduced exhaust-system weight
- More aggressive exhaust sound
- Improved flat-six exhaust character
Removes The Factory Secondary Catalytic Converters:
- The principal function of this product is to replace the original secondary catalytic converters.
- Instead of forcing exhaust gases through the catalyst substrates, the bypass pipes provide a direct, straight-through path.
- This makes the system less restrictive and substantially lighter than the original catalyst assemblies.
- Because the secondary catalytic converters are removed completely, these pipes are intended for competition, closed-course and off-road applications rather than normal emissions-controlled road use.
Why Upgrading Matters:
The factory secondary catalytic converters do not need to have failed before installing this product.
These bypass pipes are primarily a performance, weight-saving and sound upgrade for competition-oriented vehicles.
Reasons for upgrading include:
- Removes restrictive secondary catalytic converters
- Straight-through exhaust path
- Reduced exhaust backpressure
- Improved exhaust flow
- Manufacturer-reported +8 WHP
- Improved throttle response
- Approximately 25 lb weight reduction
- Enhanced flat-six exhaust note
- T304L stainless-steel construction
- CNC mandrel-bent tubing
- Bolt-on installation
- No cutting or welding required
- Designed specifically for 2000–2004 Porsche 986 models
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.
