Fabspeed Sport Highflow Catalytic Converter. Porsche 964 Carrera (1989-1994)  ❭  FSPOR964SC

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.
