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.
