Product Information

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
Stronger air-cooled flat-six sound
Resonated design to control rasp
T304L stainless-steel construction
Straightforward bolt-on installation

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

FSPOR911SC

Product Information

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.
