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.

The Fabspeed Porsche 986 Boxster Race Headers are a competition-focused exhaust upgrade designed for maximum exhaust flow, improved scavenging, reduced restriction and sharper engine response on 2000–2004 Porsche 986.2 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
Unlike Fabspeed's Sport Headers, these Race Headers do not contain catalytic converters. They replace the factory Porsche headers and their integrated primary catalysts with free-flowing equal-length headers, making them intended specifically for closed-course competition, race and off-road applications.
Constructed from equal-length T304 stainless-steel CNC mandrel-bent tubing, the headers use F1-style merge collectors to improve exhaust-gas velocity and scavenging. They can be used with the factory rear muffler or compatible aftermarket cat-back exhaust systems designed around the OEM mounting arrangement.
What This Product Does:
Headers collect exhaust gases as they leave the engine's cylinder heads and direct them into the remainder of the exhaust system.
The design, length and geometry of the individual primary tubes influence how efficiently these gases leave each cylinder.
The Fabspeed Race Headers replace the original catalyst-equipped manifolds with a freer-flowing, equal-length arrangement.
They are designed to provide:
- Maximum exhaust-gas flow
- Reduced exhaust restriction
- Reduced backpressure
- Improved exhaust scavenging
- Improved cylinder evacuation
- Increased performance potential
- Sharper throttle response
- Improved high-RPM breathing
- Reduced exhaust-system weight
- More aggressive flat-six exhaust sound
Removes The Factory Catalytic Converters:
- On 2000–2004 Porsche 986 Boxster models, the factory headers incorporate primary catalytic converters.
- The Fabspeed Race Headers remove these catalysts entirely.
- This creates a substantially less restrictive exhaust path but also means the product is fundamentally different from a street-oriented catalyst-equipped replacement header.
- The Race Headers are intended for vehicles where maximum exhaust flow is prioritised over emissions-system compatibility.
Why Upgrading Matters:
The factory headers do not need to have failed before installing this product.
These Race Headers are primarily a competition performance upgrade.
Reasons for upgrading include:
- Removes restrictive OEM catalytic converters
- Maximum exhaust-flow design
- Equal-length primary tubes
- T304 stainless-steel construction
- CNC mandrel-bent tubing
- F1-style merge collectors
- Improved exhaust scavenging
- Reduced exhaust backpressure
- Improved throttle response
- Increased performance potential
- Reduced exhaust-system weight
- More aggressive flat-six sound
- O2 sensor bungs incorporated
