Fabspeed Sport Cat. Porsche 911 Carrera (1976-1989)  ❭  FSPOR911SC

Fabspeed Sport Cat.
The Fabspeed Porsche 911 Carrera Sport Cat is a high-flow catalytic converter designed as a direct bolt-on replacement for the heavy and restrictive factory catalyst fitted to classic Porsche 911 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  

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

The primary performance benefit is reduced exhaust restriction and improved throttle response rather than a dramatic increase in peak horsepower.

These are manufacturer-reported figures from specific testing and should not be considered guaranteed results for every vehicle.

Actual performance can vary depending on:

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

Why Upgrading Matters:
The original catalytic converter does not necessarily need to have failed before a Sport Cat is installed.

The Fabspeed unit can also be selected as a performance exhaust upgrade.

Potential benefits include:

• 300-cell high-flow catalyst
• Reduced exhaust restriction
• Improved throttle response
• Slight horsepower and torque improvement
• Approx. 9 lb weight saving
• Sportier exhaust tone
• T304L stainless-steel construction
• Integrated O2 sensor bung
• Direct bolt-on installation
• No cutting or welding required

This makes the Sport Cat particularly relevant for owners who want a freer-flowing catalytic exhaust configuration rather than using a completely catless bypass pipe.
