The Fabspeed Porsche 996 Carrera Competition Link Pipe / Cat Bypass X-Pipe is a performance exhaust component designed for closed-course competition and off-road applications. It replaces the factory catalytic-converter section with a freer-flowing X-pipe, reducing exhaust restriction and allowing the Porsche flat-six engine to breathe more efficiently at higher engine speeds.
Fits:
- Porsche 996 C2 3.6L 1999-2004
- Porsche 996 C4 3.6L 1999-2004
Manufactured from mandrel-bent T304L stainless steel, the system is designed to improve mid- and high-RPM performance, sharpen throttle response, reduce rear-end weight and create a significantly more aggressive exhaust note.
Because this system eliminates the factory catalytic converters, it is intended strictly for closed-track and off-road use where legally permitted and should not be used on public roads where catalytic converters are required.
What This Product Does:
The standard Porsche 996 Carrera exhaust system uses catalytic converters to reduce harmful exhaust emissions.
For dedicated competition applications, the Fabspeed Cat Bypass X-Pipe replaces this catalytic-converter section with unrestricted exhaust tubing and an X-pipe crossover.
Removing the catalyst restriction allows exhaust gases to pass through the system more freely.
The system is designed to:
- Reduce exhaust backpressure
- Improve exhaust-gas flow
- Improve mid- and high-RPM performance
- Increase horsepower potential
- Increase torque
- Improve throttle response
- Reduce exhaust-system weight
- Produce a louder, more aggressive exhaust note
- Improve high-RPM engine breathing
Performance Benefits:
Fabspeed reports dyno-tested improvements of:
Horsepower: +33 WHP
Torque: +41 ft-lb
Weight Reduction: Approx. 25 lb
Fabspeed states that the system was developed to deliver its strongest gains towards the upper part of the rev range, with substantial improvements above approximately 3,500 rpm.
These are manufacturer-reported results from a particular test vehicle and are not guaranteed figures for every Porsche 996 Carrera.
Actual performance can vary according to engine condition, vehicle specification, existing modifications, ECU calibration, fuel, atmospheric conditions and testing method.
Why Upgrading Matters:
This component is primarily a competition performance upgrade, not a routine replacement for a failed factory catalytic converter.
For suitable closed-course vehicles, potential reasons for installation include:
- Reduced exhaust restriction
- Increased high-RPM exhaust flow
- Improved mid- and high-RPM performance
- Reduced rear-end weight
- Sharper throttle response
- More aggressive exhaust sound
- Simplified competition exhaust configuration
It can also form part of a broader competition exhaust package incorporating performance headers, lightweight mufflers and other track-oriented modifications.

Please note: These sport cats will make your car sound louder than with stock cats. If you have ,or intend to install sport silencers, you may find the car is a bit loo loud. We recommend to use one sport exhaust component if you are concerned about decibel levels.
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.

993 Sport Catalytic Converter X-Pipe is different for certain years. 1994-1996 1/2 993's and all 993 SUPERCUP cars (1994 to 1997 993CUP) have Bischoff oval 3 bolt flanges. 1996+1998 993's are all Gillett round 3 bolt flanges. YOU MUST CORRECTLY specify flange type when Ordering.
When in doubt go check especially the late 1995 and early 1996 cars as this was a "cross-over year" and flange style changed during the year.
T304 Stainless steel C.N.C mandrel bent with polished show car mirror shine.
