Fabspeed HJS High flow Sport Cat. 

The Fabspeed HJS High-Flow Sport Catalytic Converter is a performance exhaust upgrade for the Porsche 964 Turbo, C2 Turbo designed to replace an ageing, restrictive or previously removed original catalytic converter.

Fits:

• Porsche 964 (911) TURBO 3.3L 1990-94
• Porsche 964 (911) TURBO 3.6L 1990-94

At the heart of the system is a 200-cell HJS high-flow catalytic converter, engineered to reduce exhaust emissions while providing substantially less restriction than older factory catalyst technology. The system is manufactured using 14–16 gauge CNC mandrel-bent T304L stainless steel, providing a durable, corrosion-resistant exhaust path designed for improved gas flow.

By reducing exhaust restriction after the turbocharger, the sport catalyst can help the turbocharged flat-six breathe more efficiently, supporting improved throttle response and performance while retaining catalytic exhaust-gas treatment.

What This Product Does:

• Replaces the original catalytic converter section.
• Converts harmful exhaust pollutants before gases leave the exhaust system.
• Provides significantly greater exhaust flow than an ageing or restrictive factory catalyst.
• Reduces exhaust backpressure after the turbocharger.
• Helps improve throttle response.
• Can support improved turbo response and engine performance.
• Provides a performance-oriented alternative to an original 1990s catalytic converter.
• Restores catalytic-converter functionality on vehicles where the original catalyst has previously been removed.
• Uses a high-flow 200-cell HJS catalyst rather than a conventional dense factory-style catalyst.
• Uses stainless-steel construction for corrosion resistance and durability.
• Retains catalytic treatment while offering flow characteristics closer to a less restrictive exhaust system.

Fabspeed states that its HJS high-flow catalysts can flow at more than 90% of the rate of a straight pipe in applicable installations while still providing catalytic exhaust-gas treatment.

Symptoms Of Wear Or Failure:
An original catalytic converter can deteriorate internally after decades of heat cycles, vibration and exposure to exhaust gases.

Possible symptoms include:

• Noticeable loss of engine power.
• Poor throttle response.
• Sluggish turbo response.
• Engine feeling restricted at higher RPM.
• Difficulty achieving full boost or performance.
• Excessive exhaust backpressure.
• Increased exhaust temperatures.
• Rattling noises from inside the catalytic converter.
• Metallic noises caused by a loose or broken catalyst core.
• Strong or unusual exhaust smells.
• Failed emissions testing.
• Increased exhaust emissions.
• Catalyst housing becoming excessively hot.
• Reduced fuel economy.
• Engine running poorly under load.
• Visible corrosion or damage to the original converter.
• Exhaust leaks around the converter or flanges.

A partially blocked catalyst may allow the engine to run reasonably well at low speed but restrict exhaust flow increasingly as engine speed and load rise.

Why Replacement Matters:
The catalytic converter sits directly in the exhaust path, so its internal condition has a major influence on both emissions performance and exhaust flow.

As the catalyst ages, the internal substrate can deteriorate, melt, become contaminated or break apart. A damaged catalyst may become increasingly restrictive, creating excessive exhaust backpressure.

On a turbocharged engine, restriction after the turbocharger is particularly undesirable because the turbocharger must push exhaust gases through the converter.

Replacing a worn or restrictive converter can help restore:

• Proper exhaust flow.
• Turbocharger response.
• Throttle response.
• Engine performance.
• Exhaust-gas treatment.
• Correct operating temperatures.
• Reliable exhaust-system operation.

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.

Fabspeed RENNKRAFT Sport Cat And Comp.

The Fabspeed RENNKRAFT Sport Cat and Competition Link Pipe system is a performance exhaust upgrade designed for the Porsche 964 Turbo. It replaces the restrictive original catalytic converter section with Fabspeed's interchangeable RENNKRAFT system, allowing the exhaust configuration to be changed between an HJS 200-cell high-flow sport catalytic converter and a straight-through competition link pipe.

Fits:

• Porsche 964 (911) TURBO 3.3L 1990-94
• Porsche 964 (911) TURBO 3.6L 1990-94  

The sport catalyst configuration is designed to improve exhaust flow while retaining catalytic exhaust-gas treatment, while the competition link pipe provides the least restrictive exhaust path for appropriate track and competition use.

The system retains the original Porsche rear mufflers, allowing the vehicle to preserve a largely factory rear appearance while benefiting from reduced exhaust restriction, a stronger exhaust character and more noticeable turbocharger sound.

Constructed from 3-inch, 14–16 gauge T304L stainless-steel tubing, the system uses CNC mandrel bends to maintain a smooth internal exhaust path and provide durability under the high temperatures generated by the turbocharged flat-six engine.

What This Product Does:

• Replaces the restrictive original catalytic-converter section.
• Provides interchangeable sport-cat and competition-pipe configurations.
• Uses a high-flow HJS 200-cell catalytic converter in the catted configuration.
• Reduces exhaust restriction after the turbocharger.
• Helps improve exhaust-gas flow.
• Can help reduce turbo lag.
• Supports improved turbocharger response.
• Produces a more pronounced exhaust note.
• Increases audible turbo whistle.
• Retains the original Porsche rear mufflers.
• Allows the vehicle to maintain a relatively factory-looking rear exhaust installation.
• Provides a straight-through competition configuration for suitable track applications.
• Uses stainless-steel construction for long-term corrosion resistance.
• Provides a direct replacement for the factory catalytic-converter section.

Fabspeed states that the HJS 200-cell catalyst flows approximately 93% as much as a straight pipe, providing a balance between catalytic treatment and performance-oriented exhaust flow.

Symptoms Of Wear Or Failure:
A Porsche 964 Turbo's original catalytic converter can deteriorate after decades of heat cycles, vibration and exposure to high exhaust temperatures.

Possible signs of deterioration or restriction include:

• Reduced engine power.
• Sluggish acceleration.
• Slow turbo response.
• Increased turbo lag.
• Engine feeling restricted at higher RPM.
• Poor performance under heavy load.
• Excessive exhaust backpressure.
• Increased exhaust-gas temperatures.
• Unusual heat around the catalytic converter.
• Rattling from inside the converter.
• Metallic noises caused by a loose catalyst substrate.
• Strong or unusual exhaust smells.
• Failed emissions testing.
• Increased exhaust emissions.
• Visible corrosion or damage to the converter housing.
• Exhaust leaks around flanges or joints.

A partially blocked catalyst may allow relatively normal operation at low engine speeds but increasingly restrict exhaust flow as engine speed and load increase.

Why Replacement Matters:
The catalytic converter sits directly downstream within the turbocharged exhaust system, meaning its ability to flow exhaust gases can have a significant influence on engine and turbocharger performance.

As an old catalyst deteriorates, its internal substrate can:

• Break apart.
• Become contaminated.
• Melt or deform.
• Collapse internally.
• Become increasingly restrictive.

A restricted catalyst creates additional pressure after the turbocharger, making it more difficult for exhaust gases to leave the turbine efficiently.

Replacing an ageing or restrictive factory catalyst with a correctly designed high-flow system can help restore:

• Efficient exhaust flow.
• Turbocharger response.
• Throttle response.
• High-RPM performance.
• Correct exhaust-system operation.
• More consistent engine performance.
• A stronger performance exhaust character.

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.
