Fabspeed 2nd Link Comp Pipes.
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.

Fabspeed Competition Conversion Kit - For Fabspeed Valved Exhaust. 

The Fabspeed Porsche 981 Cayman GT4 / Boxster Spyder Competition Conversion Kit is a lightweight performance exhaust upgrade designed to transform an existing Fabspeed Motorsport Valvetronic Exhaust System into a louder, lighter and more aggressive competition-style exhaust configuration.

Fits:

• Porsche Boxster 981 Spyder 3.8L 2016
• Porsche Cayman GT4 3.8L 2015-16  

Developed specifically for the Porsche 981 Cayman GT4 and Boxster Spyder models manufactured between 2015 and 2016, this conversion kit eliminates the valved exhaust section of the compatible Fabspeed system and replaces it with direct-flow stainless steel muffler bypass pipes.

The result is an uncompromising exhaust configuration that emphasises the distinctive sound of Porsche's naturally aspirated 3.8-litre flat-six engine.

The original Fabspeed Valvetronic Exhaust System provides adjustable exhaust sound through its electronically controlled, vacuum-actuated valve arrangement. This allows the driver to switch between quieter and more aggressive exhaust characteristics.

However, for Porsche enthusiasts who prefer maximum exhaust volume and a more focused motorsport experience, the additional valve hardware and associated sound-control features may no longer be required.

Fabspeed developed the Competition Conversion Kit to provide a straightforward alternative.

By replacing the valved section with fixed, free-flowing bypass pipes, the kit removes the need for exhaust valve operation in that section and delivers a consistently aggressive exhaust note.

Manufactured in-house by Fabspeed Motorsport from high-quality T304L stainless steel, the conversion pipes use a 2.5-inch (63.5 mm) diameter design to maintain an unrestricted exhaust path.

The kit also reduces exhaust system weight by approximately 11 lbs (5 kg) compared with the corresponding valved portion of the Fabspeed Motorsport exhaust.

This weight saving contributes to a lighter exhaust configuration, particularly desirable for track-focused vehicles where reducing unnecessary mass is an important consideration.

Installation is designed to be straightforward. The competition pipes bolt directly into the existing Fabspeed exhaust arrangement using the current Fabspeed AccuSeal clamps.

No cutting or welding is required, and the modification is reversible, allowing the original Fabspeed valved section to be reinstalled if a quieter exhaust configuration is required.

The Competition Conversion Kit is particularly suitable for dedicated track cars, motorsport-inspired builds and Porsche owners seeking the most aggressive sound available from their compatible Fabspeed exhaust system.

Important: This kit is only suitable for Porsche 981 Cayman GT4 and Boxster Spyder vehicles already equipped with the corresponding Fabspeed Motorsport Valvetronic Exhaust System. It is not compatible with the standard Porsche factory exhaust.

What This Product Does:
The Fabspeed Competition Conversion Kit replaces the valved section of the existing Fabspeed Motorsport Valvetronic Exhaust System with straight-through muffler bypass pipes.

Its primary functions include:

• Converts the Valved Exhaust into a Competition Configuration: Replaces the relevant valved section with fixed, direct-flow exhaust pipes.
• Eliminates Exhaust Valve Operation: Removes the adjustable sound-control function from the converted section.
• Creates a Louder Exhaust Note: Produces a consistently aggressive exhaust sound without the quieter valve setting.
• Enhances Flat-Six Engine Sound: Makes the distinctive 3.8-litre naturally aspirated Porsche engine more prominent.
• Reduces Exhaust Weight: Saves approximately 11 lbs compared with the original Fabspeed Valvetronic section.
• Provides Direct Exhaust Gas Flow: Uses straight-through pipework instead of the valved muffler arrangement.
• Supports Motorsport Applications: Provides a lightweight, high-volume exhaust configuration for appropriate track-focused use.
• Maintains Stainless Steel Durability: T304L stainless steel construction offers resistance to corrosion and high exhaust temperatures.
• Preserves Compatible Fabspeed Connections: Uses the existing exhaust mounting arrangement and AccuSeal clamps.
• Allows Reversible Conversion: The original Fabspeed valved section can be reinstalled without permanent exhaust modification.
• Simplifies the Converted Exhaust Section: Eliminates the valves and their moving mechanisms from the replaced portion of the system.
• Maintains the Existing Catalytic Converters: As a cat-back conversion, it does not require removing the vehicle's catalytic converters.

Symptoms Of Wear Or Failure:
The Fabspeed Competition Conversion Kit is primarily an exhaust performance upgrade, not a routine maintenance component.

However, it may also be considered when an existing compatible Valvetronic exhaust section has become damaged or when an owner wishes to eliminate the associated valve mechanism.

Common problems affecting the existing exhaust system include:

• Exhaust sound does not change when the valves are operated.
• A valve becomes stuck open or closed.
• Inconsistent response from the valve system.
• Metallic rattling around the valve assembly.
• Irregular or incomplete valve movement.
• Ticking, hissing or blowing sounds.
• Unexpected exhaust noise.
• Soot marks around pipe connections.
• Exhaust fumes near the vehicle.
• Increased noise under acceleration.
• Heavy rust or corrosion.
• Weakened welds.
• Cracked mounting points.
• Perforated pipe sections.
• Loose or damaged hardware.

Why Replacement / Upgrading Matters:
Installing the Fabspeed Competition Conversion Kit changes the character and weight of an existing Valvetronic exhaust system.

The main advantages are reduced weight, simplified exhaust construction and a more aggressive, consistently loud exhaust note.

• Maximum Exhaust Sound: Removes the quieter valved operating mode and delivers a consistently aggressive exhaust character.
• Motorsport-Inspired Driving Experience: Emphasises the sound of the Porsche 981 GT4 and Spyder's naturally aspirated flat-six engine.
• Approximately 11 lb Weight Reduction: Eliminates weight associated with the replaced Valvetronic section.
• Simplified Exhaust Arrangement: Removes moving exhaust valve mechanisms from the converted section.
• Direct Exhaust Flow: Uses 2.5-inch stainless steel bypass pipes.
• Durable Stainless Steel Construction: Manufactured from corrosion-resistant T304L stainless steel.
• Compatible with Existing Fabspeed Systems: Designed specifically for the corresponding Fabspeed Valvetronic Exhaust.
• Reversible Modification: Allows the original valved components to be reinstalled.
• No Cutting or Welding: Uses the existing exhaust connections for bolt-on installation.
• Ideal for Track-Focused Builds: Provides a lighter, louder exhaust configuration.
• Reduced Dependence on Valve Components: Eliminates valve-related mechanical operation from the replaced section.
• Fabspeed Motorsport Engineering: Manufactured by a specialist performance exhaust producer.

Fabspeed Competition Race Exhaust System.

The Fabspeed Spec Boxster Competition Race Exhaust System is a lightweight, high-flow exhaust package developed specifically for 1997–1999 Porsche 986 Boxster and Boxster S track and competition applications.

Fits:

• Porsche Boxster 986 2.5L 1997-99
• Porsche Boxster 986 2.7L 1999
• Porsche Boxster S 986 3.2L 1999  

Designed with maximum exhaust flow, weight reduction and performance in mind, the system replaces the restrictive factory exhaust and catalytic-converter arrangement with a much freer-flowing race configuration.

Fabspeed manufactures the system from 14–16 gauge CNC mandrel-bent T304 stainless steel, providing excellent resistance to exhaust heat, corrosion and repeated track-day thermal cycling.

The system also includes turn-down exhaust tips, designed to help direct sound toward the ground and assist with track noise-limit compliance.

Fabspeed currently publishes performance figures of approximately:

• +15 hp
• +14 lb-ft of torque
• 36 lb / 16.4 kg weight reduction

Actual performance will vary according to vehicle condition, engine specification, fuel and testing conditions.

What This Product Does:
The factory exhaust system must balance noise, emissions, refinement and performance.

For a dedicated competition car, these compromises can create unnecessary weight and exhaust restriction.

The Fabspeed Spec Boxster Competition system is designed to:

• Maximise exhaust gas flow
• Reduce backpressure
• Improve throttle response
• Increase horsepower and torque
• Reduce rear vehicle weight
• Produce a much more aggressive race exhaust note
• Remove the restrictive factory catalytic converters
• Provide a lightweight track-focused exhaust layout
• Direct exhaust sound downward through turn-down tips
• Replace the full OEM exhaust with a competition-oriented system

This system is specifically intended for race and track use, rather than normal road driving.

Symptoms Of Wear Or Failure:
The factory 986 exhaust system is now several decades old on early cars and can deteriorate through heat, condensation, corrosion and vibration.

Common symptoms include:

• Rust or corrosion on exhaust pipes and silencers
• Cracked welds
• Blowing or hissing noises
• Black soot around leaking joints
• Internal muffler rattles
• Loose internal baffles
• Catalyst rattling
• Reduced engine performance
• Restricted high-RPM response
• Excessive exhaust heat
• Loose clamps or brackets
• Damaged exhaust hangers
• Dented or distorted pipework
• Exhaust fumes around the rear of the vehicle
• Poor exhaust-tip alignment
• Check Engine Light caused by catalyst-related faults

Rattling or reduced performance may also be caused by heat shields, oxygen sensors or other engine-management issues, so proper diagnosis is recommended.

Why Replacement Matters:
A deteriorated exhaust system can affect both performance and reliability.

Cracked or leaking exhaust components can allow extremely hot gases to escape near surrounding parts.

Restricted or internally damaged catalytic converters can also increase exhaust backpressure.

Continued operation with a failing exhaust can contribute to:

• Reduced engine performance
• Poor throttle response
• Excessive exhaust heat
• Unwanted noise and rattling
• Exhaust fumes escaping before the intended outlet
• Heat exposure to nearby components
• Additional stress on exhaust mounts and joints

Replacing damaged components restores secure exhaust routing and correct exhaust flow.

For a healthy standard car, the Fabspeed Competition system is primarily a race-performance and weight-reduction upgrade.
