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

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.

SOUND: The new 2.9l “hot V” V6 is a great sounding engine but unfortunately the restrictive OEM catalytic converters choke the sound. These Sport Cats flow 93-95% of a straight pipe and really let this engine sing. Expect a significant increase in exhaust growl and turbo sounds. Pops, bangs and crackles will be much louder and sharper. Best of all, there is no interior drone whatsoever.

The Porsche Macan is Porsche's most popular model and boasts the highest volume of sales. The Macan is a true enthusiast car, and dramatically benefits from a Fabspeed Sport Cat. You'll appreciate the more aggressive exhaust note and significant horsepower increase.
These are the largest and highest flowing catalytic converters on the market for the 2019-2021 Macan 2.0 liter 4 cylinder turbocharged car. We use HJS German Imported 200 CPSI trimetallic EXTRA LARGE catalyst cores which allow for maximum exhaust flow with the worlds very best catalysts efficiency for emissions compliant reliable power. Fabspeed engineers have worked tirelessly to create a direct bolt-on replacement for the heavy & restrictive factory Macan single catalytic converter that is 700 cells ceramic core that is 10” 250mm long.
Our Fabspeed engineers immediately found an opportunity for improvement to OEM stock Porsche catalyst system when they found restrictive OEM 700 cell ceramic catalytic converter. The OEM Cat restricts exhaust CFM flow, limits sound and worst of all, rob performance. Replacing the OEM cat for a Fabspeed Sport Cat will net you improved performance with absolutely zero fear of a check engine light.
