Please note: This is a special-order item manufactured to order. In some cases, please allow 4 – 5 weeks for the delivery. Special order items cannot be cancelled from this supplier once your order has been placed.
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.

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:
- Porsche 944 Turbo 2.5L 8V 1985-88
- Porsche 944 Turbo 2.5L 8V 1989-91
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.

- Reduce exhaust restriction and backpressure.
- Improve throttle response and power delivery.
- Enhance exhaust sound and character.
- Improve engine efficiency and breathing.
- Upgrade exhaust aesthetics and build quality.
A high-flow exhaust system plays a key role in unlocking engine performance.
Why Do Standard Exhaust Systems Fail or Limit Performance?
Factory exhaust systems are designed to prioritise emissions
compliance, cost efficiency, and sound suppression. Over time, they can suffer
from:
- Restrictive internal baffling reducing performance.
- Corrosion from moisture and repeated heat cycles.
- Excessive weight limiting efficiency.
- Muted exhaust sound lacking engagement.
- Reduced compatibility with performance tuning upgrades.
As engines are pushed harder, standard exhausts can become a performance bottleneck.
Why Upgrade to a Fabspeed Exhaust?
Fabspeed exhaust systems are designed for drivers seeking performance-focused enhancements.
Upgrade Benefits:
- Improved exhaust flow for increased performance.
- Sportier, more aggressive exhaust sound.
- Lightweight, durable stainless steel construction.
