The Fabspeed Porsche 996 Turbo Cat Bypass Pipes are high-performance exhaust components developed for the Porsche 911 Turbo (996), designed specifically for use with compatible existing Fabspeed exhaust systems.
Fits:
- Porsche 996 TURBO 2000-05
Manufactured from premium 14–16 gauge T304L stainless steel, these catalyst-bypass pipes replace the sport catalytic converter sections of the Fabspeed exhaust with straight-through pipework.
Their purpose is to provide a less restrictive exhaust path, producing a more aggressive exhaust note and supporting improved exhaust gas flow from the Porsche 996 Turbo's twin-turbocharged 3.6-litre flat-six engine.
By removing the catalytic converter elements from the exhaust path, the bypass pipes eliminate a source of exhaust restriction and create a more direct route for gases leaving the turbochargers.
Fabspeed designs these pipes for owners seeking a more extreme, motorsport-oriented exhaust configuration.
The system uses CNC mandrel-bent stainless steel tubing to provide smooth internal pipe geometry, consistent exhaust routing and durable construction.
Fabspeed describes the pipes as a direct bolt-on alternative to the corresponding catalytic converter sections in its compatible exhaust systems.
A key feature of this product is its modular compatibility with existing Fabspeed exhaust components, including suitable Maxflo and Supersport X-Pipe configurations.
However, these are not universal catalyst replacement pipes.
They do not fit directly onto the original Porsche factory exhaust or exhaust systems manufactured by other aftermarket suppliers.
Fabspeed lists a weight reduction of approximately 25 lb (11.3 kg), although the precise saving will depend on the configuration being replaced.
The manufacturer also states that the pipes can improve power delivery and throttle response, but does not publish a confirmed horsepower or torque increase for this standalone product.
What This Product Does:
The Fabspeed Cat Bypass Pipes replace the catalytic converter sections of a compatible Fabspeed Porsche 996 Turbo exhaust.
In a conventional catalytic exhaust, exhaust gases pass through a catalytic converter containing a coated internal substrate.
The converter treats pollutants in the exhaust gases, but its internal structure also creates a degree of flow resistance.
Fabspeed's bypass pipes replace those sections with straight-through tubing, eliminating the catalytic converter substrate from the exhaust path.
The main functions and benefits include:
- Creates a Straight-Through Exhaust Route: Replaces the existing Fabspeed sport catalytic converter sections with unrestricted pipework.
- Reduces Exhaust Restriction: Removes the catalytic substrate from the exhaust gas path.
- Supports Increased Exhaust Flow: Provides a less restrictive route for gases leaving the turbochargers.
- Enhances Motorsport Exhaust Sound: Produces a louder, sharper and more aggressive exhaust character.
- Improves Performance Potential: Designed to support stronger power delivery in suitable performance configurations.
- Supports Throttle Responsiveness: Fabspeed advertises improved throttle response.
- Reduces Exhaust System Weight: Fabspeed lists a weight reduction of approximately 25 lb.
- Uses Corrosion-Resistant Stainless Steel: T304L construction offers durability under high exhaust temperatures.
- Maintains Smooth Pipe Geometry: CNC mandrel bending helps preserve consistent internal tubing dimensions.
- Integrates with Compatible Fabspeed Systems: Designed for selected existing Maxflo and Supersport X-Pipe exhaust configurations.
- Supports Motorsport Preparation: Provides a catalyst-free configuration for vehicles used in permitted competition or closed-course environments.
- Allows Modular Exhaust Configuration: Enables compatible Fabspeed exhaust systems to use either the appropriate catalytic converter sections or the bypass configuration.
Symptoms Of Wear Or Failure:
The Fabspeed Cat Bypass Pipes are primarily a motorsport performance modification, not a standard maintenance replacement.
However, owners may be considering them while inspecting deteriorated exhaust components or preparing a dedicated track vehicle.
1. Corroded Exhaust Pipework
Exposure to moisture, heat and environmental contamination can cause corrosion around exhaust pipes, joints and flanges.
Advanced corrosion may weaken the affected sections and lead to leakage.
2. Cracked Exhaust Welds
Repeated heating and cooling, vibration or mechanical stress can contribute to cracks around welded joints.
Possible signs include exhaust blowing noises and visible soot deposits.
3. Exhaust Leaks
Damaged flanges, failed gaskets or cracked pipework can allow exhaust gases to escape before reaching the tailpipes.
Exhaust leaks may create hissing, blowing or ticking sounds.
4. Restricted Catalytic Converters
A damaged or internally deteriorated catalyst may become partially blocked.
A significant restriction can increase exhaust backpressure and reduce engine performance.
5. Loose Catalytic Converter Substrate
Damage within a catalytic converter may cause internal rattling or metallic vibration.
These noises can sometimes change with engine speed or load.
6. Reduced Engine Performance
Excessive exhaust restriction may contribute to reduced power or sluggish acceleration.
However, poor performance can also be caused by ignition faults, boost leaks, faulty sensors or turbocharger problems.
7. Unusual Exhaust Temperatures
Severe restrictions or engine combustion faults may contribute to abnormal exhaust temperatures.
The cause should be diagnosed before any performance modification is made.
8. Damaged Exhaust Flanges
Corroded or distorted flanges may prevent exhaust sections from sealing correctly.
9. Deteriorated Mounting Hardware
Loose or damaged exhaust fasteners can cause movement, rattling and leaks.
10. Unwanted Exhaust Vibration
Poor alignment, damaged supports or cracked components may produce vibration or metallic contact with the surrounding bodywork.
11. Exhaust-Related Diagnostic Faults
Catalytic converter efficiency faults or exhaust sensor problems may trigger an engine warning light.
The underlying cause requires proper diagnosis rather than simply removing the converter.
12. Visible Impact Damage
Exhaust pipes or catalytic converter housings may be damaged by road debris, contact with obstacles or incorrect lifting procedures.
Why Replacement / Upgrading Matters:
- The exhaust system is an important part of the Porsche 996 Turbo's engine operation.
- Exhaust gases drive the turbochargers before passing through the downstream exhaust components.
- The design of the exhaust system can influence gas flow, pressure and the sound characteristics of the vehicle.
- For a dedicated competition or closed-track Porsche 996 Turbo, Fabspeed Cat Bypass Pipes provide a way to configure an existing Fabspeed exhaust for reduced downstream restriction.
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.
