Fabspeed Exhaust
- Porsche 996 C2 3.6L 09/01-2005
- Porsche 996 C4 3.6L 09/01-2005
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.

- Porsche 996 C4 3.6L 09/01-2005
The Fabspeed Porsche 996 Carrera Muffler Bypass Pipes are a performance exhaust upgrade designed to replace the heavy factory rear side mufflers with lightweight, straight-through exhaust pipes.
Fits:
- Porsche 996 C2 3.6L 1999-2004
- Porsche 996 C4 3.6L 1999-2004
Designed for drivers seeking maximum exhaust sound, reduced rear-end weight and improved exhaust flow, these bypass pipes remove the sound-deadening restriction of the original mufflers and create a much more aggressive, motorsport-inspired flat-six exhaust note.
Manufactured from mandrel-bent T304L stainless steel, the pipes provide a direct bolt-on installation without requiring cutting or welding.
What This Product Does:
The factory rear mufflers reduce exhaust noise by directing exhaust gases through internal chambers and sound-attenuating passages.
While this provides a quieter and more refined driving experience, the mufflers also add considerable weight and create some resistance to exhaust flow.
The Fabspeed Muffler Bypass Pipes replace these factory mufflers with much simpler straight-through pipework.
This is designed to:
- Reduce exhaust restriction
- Improve exhaust-gas flow
- Reduce rear-end weight
- Increase exhaust volume
- Produce a more aggressive flat-six sound
- Improve engine response
- Support increased horsepower and torque
- Create a motorsport-inspired exhaust character
Straight Through Exhaust Design:
- Rather than passing through a conventional silencer, exhaust gases travel through the bypass pipes with minimal sound attenuation.
- This creates a much more direct exhaust path.
- Reduced restriction can help the engine evacuate exhaust gases more efficiently, particularly when combined with other performance exhaust components.
- The trade-off is a substantial increase in exhaust volume.
Performance Benefits:
Fabspeed reports dyno-tested gains of:
Horsepower: +23 WHP
Torque: +45 ft-lb
Weight Reduction: Over 35 lb
Fabspeed states that the power and torque improvements are carried throughout the RPM range.
These figures are manufacturer-reported results from a particular test vehicle and should not be considered guaranteed output for every Porsche 996 Carrera.
Actual results can vary according to:
- Engine condition
- Vehicle specification
- Existing exhaust components
- Intake modifications
- ECU calibration
- Fuel quality
- Ambient conditions
- Dyno type and testing procedure
Why Upgrading Matters:
The Fabspeed Muffler Bypass Pipes are primarily a performance and sound upgrade, rather than a routine replacement part.
The original mufflers do not need to have failed before these pipes can be installed.
Reasons for upgrading can include:
- Maximum exhaust sound
- Reduced exhaust restriction
- Significant rear weight reduction
- Increased horsepower potential
- Increased torque potential
- More aggressive throttle response
- Motorsport-inspired exhaust character
- Simplified straight-through exhaust routing
They can be particularly attractive for track-focused Porsche 996 Carrera builds where weight reduction and exhaust character take priority over cabin refinement.

- Porsche 996 C4 3.6L 09/01-2005
The Fabspeed Porsche 996 Carrera Sport Catalytic Converter X-Pipe is a high-performance exhaust upgrade designed to replace the restrictive factory catalytic-converter section while retaining catalytic emissions treatment.
Fits:
- Porsche 996 C2 3.6L 1999-2004
- Porsche 996 C4 3.6L 1999-2004
Combining a specially developed X-pipe crossover with integrated 200-cell HJS Sport Catalytic Converters, the system is designed to improve exhaust-gas flow, increase horsepower and torque, reduce rear-end weight and enhance the distinctive Porsche flat-six exhaust note.
Constructed from mandrel-bent T304L stainless-steel tubing, the system provides a performance-focused alternative to the factory catalytic converters without using catalyst-bypass pipes.
What This Product Does:
The catalytic-converter section performs two important functions within the exhaust system.
First, it routes exhaust gases from the engine towards the rear mufflers. Second, the catalytic converters chemically process harmful exhaust pollutants before the gases leave the vehicle.
The Fabspeed Sport Catalytic Converter X-Pipe retains catalytic-converter functionality while providing a higher-flow exhaust path.
Its design is intended to:
- Reduce exhaust restriction
- Improve exhaust-gas flow
- Improve mid-range torque
- Improve high-RPM horsepower
- Enhance throttle response
- Reduce exhaust-system weight
- Produce a more sporting flat-six exhaust note
- Retain catalytic emissions treatment
Performance Benefits:

These figures are manufacturer-reported results and should not be considered guaranteed output for every vehicle.
Actual performance can vary depending on:
- Engine condition
- Vehicle specification
- Fuel quality
- Existing exhaust modifications
- Intake modifications
- ECU calibration
- Ambient conditions
- Dyno type and testing procedure
Why Upgrading Matters:
The Fabspeed Sport Catalytic Converter X-Pipe is also a performance upgrade, meaning the original catalytic converters do not need to have failed before the system can be installed.
Owners may choose the upgrade for:
- Increased exhaust flow
- Reduced exhaust restriction
- Improved mid-range torque

The Fabspeed Porsche 996 Carrera Sport Headers are high-performance exhaust manifolds designed to improve exhaust flow, engine response and the characteristic sound of the Porsche flat-six engine.
Fits:
- Porsche 996 C2 3.6L 1999-2004
- Porsche 996 C4 3.6L 1999-2004
Replacing the restrictive factory-style exhaust manifolds, the Fabspeed headers use equal-length, CNC mandrel-bent primary tubes to improve exhaust-gas scavenging and balance exhaust pulses between cylinders.
The headers terminate in specially designed F1-style merge collectors, creating a smoother transition for exhaust gases compared with the factory log-style collector arrangement.
Designed as a direct bolt-on replacement for the original headers, they provide a performance upgrade without requiring replacement of the entire exhaust system.
What This Product Does:
Exhaust headers collect exhaust gases leaving each cylinder and direct them towards the rest of the exhaust system.
The factory exhaust manifold must perform the same basic function, but its design can create restrictions and less-efficient interaction between individual exhaust pulses.
The Fabspeed Sport Headers are designed to provide a smoother and more efficient route for exhaust gases leaving the engine.
Their equal-length primary design helps coordinate exhaust pulses before they reach the collector.
This is intended to improve:
- Exhaust-gas flow
- Exhaust scavenging
- Cylinder-to-cylinder exhaust pulse balance
- Engine breathing
- Throttle response
- Torque delivery
- Horsepower
- Flat-six exhaust character
Performance Benefits:

- Fuel quality
- Existing exhaust modifications
- Intake modifications
- ECU calibration
- Ambient temperature
- Dyno type and testing procedure
Why Upgrading Matters:
The Fabspeed Sport Headers are primarily a performance upgrade, rather than a routine replacement component.
Owners may choose them even when their original exhaust manifolds remain serviceable.
The principal reasons for upgrading include:
- Improved exhaust flow
- Equal-length primary design
