Product Information
Fabspeed European Pre-Muffler Pipe.
The Fabspeed Porsche 964 Carrera European Pre-Muffler / Cat Bypass Pipe is a performance exhaust component designed to replace the factory catalytic converter with a freer-flowing exhaust section for competition and off-road applications.

Fits:
  • Porsche 964 (911) C2 1989-94
  • Porsche 964 (911) C4 1989-94 

Inspired by the European-style pre-muffler configuration, the pipe reduces the restriction associated with the original catalytic converter while incorporating an internal resonator to help shape the exhaust note.

Manufactured from T304L stainless steel, this lightweight exhaust upgrade is designed to improve exhaust flow, enhance throttle response and produce a stronger, more sporting air-cooled flat-six exhaust character.

Because this component removes the catalytic converter, it is intended for competition and off-road use only where legally permitted.

What This Product Does:
The standard catalytic converter processes exhaust gases to reduce harmful emissions before they leave the vehicle.

For competition applications, the Fabspeed European Pre-Muffler replaces this catalytic converter with a much freer-flowing exhaust path.

Removing the catalyst restriction allows exhaust gases to pass through the system more easily.

The pre-muffler is designed to:

  • Reduce exhaust restriction
  • Improve exhaust-gas flow
  • Improve engine breathing
  • Enhance throttle response
  • Support improved performance
  • Reduce exhaust-system weight
  • Produce a stronger exhaust note
  • Provide a European-style pre-muffler configuration

European Pre-Muffler Design:
  • Rather than using a simple straight catalyst-delete pipe, Fabspeed incorporates an internal resonator into the system.
  • This provides a freer-flowing exhaust path while helping control and shape the sound produced by the air-cooled flat-six engine.
  • The result is intended to provide a more sporting exhaust character without simply functioning as an unrestricted straight pipe.

Why Upgrading Matters:
The Fabspeed European Pre-Muffler is primarily a performance modification, rather than a routine replacement for a failed catalytic converter.

For a suitable competition or off-road Porsche 964, reasons for upgrading can include:

  • Reduced exhaust restriction
  • Improved exhaust flow
  • Improved throttle response
  • Reduced exhaust-system weight
  • More pronounced flat-six sound
  • European-style pre-muffler configuration
  • T304L stainless-steel construction
  • Direct bolt-on installation

It can also complement other performance exhaust modifications fitted to the vehicle.
