Product Information
Fabspeed Secondary Muffler Bypass Pipe.
The Fabspeed Porsche 964 Turbo / 965 / C2 Turbo Secondary Muffler Bypass Pipe is a performance exhaust upgrade designed to replace the factory secondary rear muffler with a freer-flowing stainless-steel pipe.

Fits:
  • Porsche 964 (911) TURBO 3.3L 1990-94
  • Porsche 964 (911) TURBO 3.6L 1990-94  

Designed for both 3.3L and 3.6L Porsche 964 Turbo / 965 models, the bypass pipe reduces restriction in the rear exhaust system while retaining the vehicle's catalytic converter. This provides improved exhaust flow, sharper throttle response, reduced rear-end weight and a more pronounced turbocharged flat-six exhaust note.

Manufactured from 14–16 gauge CNC mandrel-bent T304L stainless steel, the pipe is a direct replacement for the original Porsche secondary muffler.

Fabspeed lists 12 HP and 10 lb-ft for this product and states that removing the factory secondary muffler saves approximately 25 lb / 11.4 kg from the rear of the vehicle. Performance figures are manufacturer-reported and actual results will vary according to vehicle specification, condition and testing environment.

What This Product Does:
The secondary muffler is positioned downstream of the catalytic converter and is primarily responsible for reducing exhaust noise before gases exit through the rear exhaust tip.

While effective at controlling sound, the internal chambers and passages of a conventional muffler can also create resistance to exhaust flow.

The Fabspeed Secondary Muffler Bypass Pipe removes this muffler and replaces it with a freer-flowing pipe.

The upgrade is designed to provide:

  • Improved exhaust-gas flow
  • Reduced rear exhaust restriction
  • Improved throttle response
  • Increased performance potential
  • Reduced rear-end weight
  • Stronger turbocharged flat-six exhaust sound
  • More pronounced turbo whistle
  • More direct exhaust path

Improved Exhaust Flow:
Replacing the factory secondary muffler removes internal chambers and sound-control structures from this section of the exhaust.

The resulting straighter exhaust route is designed to reduce restriction.

Potential benefits include:

  • Faster exhaust-gas evacuation
  • Reduced backpressure
  • Improved turbo exhaust flow
  • Sharper throttle response
  • Improved performance throughout the RPM range

The exact difference will depend on the condition and specification of the complete engine and exhaust system.

Enhanced Turbocharged Flat-Six Sound:
Removing the secondary muffler allows considerably more of the 964 Turbo's natural exhaust character to be heard.

The result is a deeper and more pronounced turbocharged flat-six sound, accompanied by increased turbo whistle.

Drivers can expect:

  • Deeper exhaust tone
  • Increased exhaust presence
  • Stronger sound under acceleration
  • More noticeable turbo whistle
  • More pronounced flat-six character
  • Sportier overall exhaust note

The final sound will depend on the rest of the exhaust system fitted to the vehicle.

Why Upgrading Matters:
The original secondary muffler does not need to have failed before this component is installed.

This product is primarily a performance, sound and weight-reduction upgrade.

Reasons for upgrading include:

  • Removes the restrictive factory secondary muffler
  • Improves exhaust flow
  • Improves throttle response potential
  • Manufacturer-listed 12 HP / 10 lb-ft
  • Approx. 25 lb / 11.4 kg rear weight saving
  • Stronger turbocharged flat-six sound
  • More noticeable turbo whistle
  • Retains the catalytic converter
  • T304L stainless-steel construction
  • CNC mandrel-bent tubing
  • Direct replacement for the factory secondary muffler
  • Suitable for both 3.3L and 3.6L 964 Turbo applications

NOTE: In the United Kingdom, sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001. They are not MOT compliant and cannot be used on public roads. These components are intended solely for race and track use.

For vehicles manufactured before 1st March 2001, a non-type approved sports catalytic converter may be fitted, provided it offers comparable performance to the original and the vehicle continues to meet the applicable emissions standards for its age. The vehicle must still pass an MOT test.

If you are located outside the UK, please check your local laws and regulations to ensure compliance.
