Fabspeed 951 Sport Cat.
The Fabspeed Porsche 944 Turbo 951 Sport Cat is a high-flow performance catalytic converter designed to reduce exhaust restriction while retaining catalytic exhaust treatment.

Fits:

Using a 200-cell high-flow catalyst combined with mandrel-bent T304L stainless-steel tubing, the Sport Cat provides a freer-flowing exhaust path than the restrictive original catalyst arrangement. On the turbocharged Porsche 944 Turbo / 951, reducing post-turbo exhaust restriction can improve exhaust flow, throttle response and overall performance while also producing a more defined performance exhaust note.

The Sport Cat is designed to work with the Fabspeed Downpipe. It can be purchased separately for vehicles already equipped with the appropriate Fabspeed downpipe or selected together with the downpipe as a complete configuration.

What This Product Does:
The catalytic converter forms part of the exhaust system and processes exhaust gases before they leave the vehicle.

A conventional catalyst contains a structured substrate coated with catalytic materials. As hot exhaust gases pass through this substrate, chemical reactions convert harmful pollutants into less harmful compounds.

The Fabspeed Sport Cat performs this basic catalytic function while using a high-flow 200-cell design intended to reduce restriction compared with the original catalyst arrangement.

It is designed to provide:

• Improved exhaust-gas flow
• Reduced post-turbo exhaust restriction
• Improved throttle response
• Increased horsepower and torque potential
• Reduced exhaust-system weight
• Moderate increase in exhaust volume
• More defined performance exhaust note
• Catalytic exhaust-gas treatment

200-Cell High-Flow Catalyst:

• The Fabspeed system uses a 200-cell high-flow catalytic converter.
• Cell count describes the density of the passages through the catalyst substrate. A performance-oriented 200-cell design provides relatively large passages for exhaust gases while maintaining the surface area required for catalytic reactions.
• Reducing restriction is particularly relevant to a turbocharged engine because exhaust gases leaving the turbocharger still need to travel efficiently through the remainder of the exhaust system.
• A freer-flowing post-turbo exhaust can therefore support improved engine and turbocharger response.

Performance Benefits:
Fabspeed lists manufacturer-reported figures of approximately:

Horsepower: +20 HP
Torque: +18 ft-lb
Weight Reduction: Approx. 12 lb

The system is also designed to improve throttle response.

These figures are manufacturer-reported and should not be interpreted as guaranteed results for every Porsche 944 Turbo.

Actual performance can vary according to:

• Engine condition
• Turbocharger condition
• Boost pressure
• Engine calibration
• Downpipe configuration
• Other exhaust modifications
• Intake modifications
• Fuel quality
• Ambient conditions
• Testing equipment and procedure

Requires Fabspeed Downpipe:
The Sport Cat is designed specifically to work with the Fabspeed Porsche 944 Turbo Downpipe.

The Sport Cat alone cannot simply replace the complete factory catalyst arrangement without the compatible downpipe.

It can therefore be ordered:

• As a Sport Cat for a vehicle already equipped with the compatible Fabspeed downpipe
• Together with the Fabspeed downpipe as a complete configuration

The existing exhaust configuration should be confirmed before ordering.

Why Upgrading Matters:
The Fabspeed Sport Cat is also a performance upgrade, so the original catalytic converter does not necessarily need to have failed before replacement.

Reasons for upgrading include:

• 200-cell high-flow catalyst
• Reduced post-turbo exhaust restriction
• Improved exhaust flow
• Improved throttle response
• Increased horsepower and torque potential
• Approx. 12 lb weight reduction
• More defined performance exhaust sound
• Mandrel-bent T304L stainless-steel construction
• Compatibility with the Fabspeed performance downpipe
• Bolt-on installation when used with the correct downpipe

It is particularly suited to performance-oriented Porsche 944 Turbo / 951 applications where improved exhaust flow is a priority.

Featuring a 300-cell high-flow catalytic converter and mandrel-bent T304L stainless-steel construction, the Sport Cat is designed to reduce exhaust restriction while retaining catalytic exhaust-gas treatment.

Compared with the original catalytic converter, the Fabspeed Sport Cat provides improved exhaust flow, sharper throttle response, reduced weight and a slightly stronger air-cooled flat-six exhaust note.

What This Product Does:
The catalytic converter is part of the vehicle's exhaust and emissions-control system.

Exhaust gases produced during combustion contain pollutants that pass through the catalyst before leaving the exhaust system. The catalytic converter uses its internal catalyst substrate to convert harmful exhaust compounds into less harmful emissions.

The Fabspeed Sport Cat performs this basic catalytic function while using a higher-flow design intended to create less exhaust restriction than the original factory converter.

It is designed to provide:

• Catalytic exhaust-gas treatment
• Improved exhaust flow
• Reduced exhaust backpressure
• Improved throttle response
• Reduced exhaust-system weight
• Slightly increased horsepower and torque
• A sportier exhaust tone
• A modern replacement for an ageing original catalyst

300-Cell High-Flow Catalyst:

• The Sport Cat uses a 300-cell high-flow catalytic converter.
• The catalyst contains a structured internal substrate that provides the surface required for catalytic reactions while allowing exhaust gases to pass through the system.
• Compared with an older and more restrictive factory catalyst, the high-flow design is intended to reduce resistance to exhaust-gas movement.
• This can help the engine breathe more efficiently while retaining a catalytic converter in the exhaust system.

Performance Benefits:
Fabspeed reports gains of approximately:

Wheel Horsepower: +2 WHP
Torque: +2 ft-lb
Weight Reduction: Approx. 9 lb / 4.1 kg

Fabspeed European Pre-Muffler Pipe.
The Fabspeed Porsche 911 Carrera European Pre-Muffler Pipe is a performance exhaust upgrade designed for classic Porsche 911 SC and Carrera models from 1976–1989.

Fits:

• Porsche 911 1976-1977 2.7L / 1976-77 3.0 Carrera
• Porsche 911 1978-1983 3.0L / SC
• Porsche 911 1984-1986 3.2L
• Porsche 911 1987-1989 3.2L G50  

Based on the European pre-muffler concept, this component replaces the original catalytic converter with a freer-flowing, resonated exhaust section. The result is reduced exhaust restriction, improved throttle response, reduced weight and a stronger air-cooled flat-six exhaust note.

Unlike a simple straight catalyst bypass pipe, the Fabspeed European Pre-Muffler incorporates a straight-through resonator with stainless-steel wool packing. This helps produce a deeper, more refined performance exhaust tone while reducing the harsh rasp often associated with completely straight-piped exhaust systems.

What This Product Does:
The pre-muffler replaces the factory catalytic converter section of the exhaust system.

Instead of forcing exhaust gases through the restrictive catalyst substrate, the Fabspeed pipe provides a freer-flowing route towards the rear muffler.

This is designed to:

• Reduce exhaust restriction
• Improve exhaust-gas flow
• Reduce backpressure
• Improve throttle response
• Increase horsepower and torque potential
• Reduce exhaust-system weight
• Increase exhaust volume
• Enhance the classic air-cooled flat-six sound

Because the original catalytic converter is removed, the component no longer provides the emissions-treatment function of the factory catalyst.

Resonated European Design:

• Rather than using a completely empty straight pipe, Fabspeed incorporates a straight-through resonator.
• The resonator allows exhaust gases to travel through the system with minimal restriction while controlling some of the undesirable frequencies produced by an unrestricted exhaust.
• Its stainless-steel wool packing helps create a deeper, more purposeful exhaust character without the excessive rasp commonly associated with a basic straight catalyst-delete pipe.

Performance Benefits:
Fabspeed states that the European Pre-Muffler provides 16+ wheel horsepower and 15+ ft-lb of torque, together with significantly improved throttle response.

During Fabspeed DynoJet testing, peak curve gains of up to 21 WHP and 17 ft-lb at approximately 4,500 rpm were recorded, with maximum power increases of approximately 16 WHP and 16 ft-lb.

These are manufacturer-reported figures from a specific test vehicle and should not be considered guaranteed results for every Porsche 911.

Actual performance can vary depending on:

• Engine condition
• Engine specification
• Existing exhaust system
• Intake modifications
• Fuel system condition
• Ignition condition
• Engine tuning
• Fuel quality
• Ambient conditions
• Testing equipment and procedure

Why Upgrading Matters:
This product is primarily a performance exhaust modification, rather than a routine service replacement.

The original catalyst does not need to have failed before the Fabspeed pre-muffler can be installed on a vehicle intended for appropriate competition or off-road use.

Reasons for upgrading include:

• Reduced exhaust restriction
• Improved exhaust flow
• Increased horsepower potential
• Increased torque potential
• Sharper throttle response
• Approx. 8 lb weight reduction

This is designed to:

• Reduce exhaust restriction
• Improve exhaust-gas flow
• Improve throttle response
• Support increased horsepower
• Reduce rear vehicle weight
• Increase exhaust volume
• Enhance the air-cooled flat-six sound
• Create a Carrera Cup-inspired exhaust configuration

Carrera Cup Style Design:

• The bypass pipe is designed as a replica of the type of primary muffler bypass arrangement used in the Porsche Motorsport 964 Carrera Cup racing programme.
• Rather than forcing exhaust gases through the internal chambers of a conventional silencer, the straight-pipe configuration provides a more direct exhaust route.
• This creates a more performance-oriented exhaust system while retaining the vehicle's catalytic converter and secondary rear muffler when used in the standard configuration.

Performance Benefits:
Fabspeed reports approximately:

Crank Horsepower: +12 HP
Wheel Horsepower: +10 WHP
Weight Reduction: Approx. 25 lb

Fabspeed also reports improved throttle response.

Fabspeed Sport Highflow Catalytic Converter.
The Fabspeed Porsche 964 Carrera Sport High-Flow Catalytic Converter is a performance replacement for an ageing, damaged, missing or restrictive factory catalytic converter.

Fits:

• Porsche 964 (911) C2 1989-94
• Porsche 964 (911) C4 1989-94 

Designed to maintain catalytic emissions treatment while providing a freer-flowing exhaust path, the system combines a modern high-flow catalyst with CNC mandrel-bent T304L stainless-steel construction.

Compared with simply removing the catalytic converter, this system provides a performance-oriented solution that retains a functioning catalyst while improving exhaust flow and enhancing the characteristic air-cooled Porsche flat-six exhaust note.

What This Product Does:
A catalytic converter forms part of the vehicle's exhaust and emissions-control system.

Exhaust gases produced during combustion contain pollutants that need to be converted into less harmful compounds before leaving the exhaust.

The catalytic converter performs this emissions-treatment process while allowing exhaust gases to continue towards the rear silencer.

The Fabspeed Sport High-Flow Catalytic Converter performs this fundamental function while using a less restrictive performance-oriented design.

It is designed to provide:

• Catalytic emissions treatment
• Improved exhaust-gas flow
• Reduced exhaust restriction
• Improved engine breathing
• Increased horsepower potential
• Increased torque potential
• Improved throttle response
• Reduced exhaust-system weight
• Enhanced air-cooled flat-six sound

High-Flow Catalyst Design:

• The internal catalyst structure provides a large surface area for the chemical reactions required to process exhaust pollutants.
• A performance catalyst is engineered to achieve this while reducing the restriction placed on exhaust gases.
• This is particularly useful on a performance vehicle, where excessive exhaust backpressure can restrict engine breathing as airflow requirements increase.
• The Fabspeed system therefore provides an alternative to both a restrictive ageing factory catalyst and a catalyst-delete pipe.

Performance Benefits:
Fabspeed reports dyno-tested gains of:

Crank Horsepower: +28 HP
Wheel Horsepower: +24 WHP
Torque: +16 ft-lb
Weight Reduction: Approx. 9 lb

Fabspeed states that the power improvement occurs throughout the RPM range rather than being concentrated solely at maximum engine speed.

These are manufacturer-reported figures from a specific test vehicle and should not be interpreted as guaranteed results for every Porsche 964.

Actual performance can vary according to:

• Engine condition
• Existing exhaust system
• Intake modifications
• ECU calibration
• Fuel quality
• Ambient conditions
• Vehicle specification
• Testing equipment and procedure

Why Upgrading Matters:
The Fabspeed Sport High-Flow Catalytic Converter can also be installed as a performance upgrade even when the original catalyst remains functional.

Potential benefits include:

• Reduced exhaust restriction
• Improved exhaust flow
• Increased horsepower potential
• Increased torque potential
• Improved throttle response
• Reduced exhaust-system weight
• More sporting exhaust sound
• Modern catalyst technology
• Retention of catalytic emissions treatment

This makes it an alternative for owners seeking improved exhaust performance without moving to a catalyst-delete configuration.
