The Fabspeed Porsche 964 Carrera Primary Muffler Bypass Pipe is a performance exhaust upgrade designed to replace the heavy and restrictive factory centre primary muffler with a lightweight, free-flowing Carrera Cup-style straight pipe.
Fits:
- Porsche 964 (911) C2 1989-94
- Porsche 964 (911) C4 1989-94
Inspired by the exhaust arrangement used on Porsche 964 Carrera Cup competition cars, the bypass pipe reduces exhaust restriction, removes substantial weight from the rear of the vehicle and produces a stronger, more aggressive air-cooled flat-six exhaust note.
Unlike a catalytic-converter bypass pipe, this component is installed after the catalytic converter and does not remove the vehicle's catalyst.
What This Product Does:
The standard Porsche 964 exhaust system uses a primary centre muffler to reduce exhaust noise before gases continue towards the secondary rear muffler.
While effective for noise reduction and refinement, the factory primary muffler adds weight and creates additional restriction in the exhaust path.
The Fabspeed Primary Muffler Bypass Pipe replaces this silencer with a freer-flowing straight pipe.
This is designed to:
- Reduce exhaust restriction
- Improve exhaust-gas flow
- Improve throttle response
- Support increased horsepower
- Reduce rear vehicle weight
- Increase exhaust volume
- Enhance the air-cooled flat-six sound
- Create a Carrera Cup-inspired exhaust configuration
Carrera Cup Style Design:
- The bypass pipe is designed as a replica of the type of primary muffler bypass arrangement used in the Porsche Motorsport 964 Carrera Cup racing programme.
- Rather than forcing exhaust gases through the internal chambers of a conventional silencer, the straight-pipe configuration provides a more direct exhaust route.
- This creates a more performance-oriented exhaust system while retaining the vehicle's catalytic converter and secondary rear muffler when used in the standard configuration.
Performance Benefits:
Fabspeed reports approximately:
Crank Horsepower: +12 HP
Wheel Horsepower: +10 WHP
Weight Reduction: Approx. 25 lb
Fabspeed also reports improved throttle response.
These figures are manufacturer-reported results from specific testing and should not be considered guaranteed output for every Porsche 964.
Actual performance can vary depending on:
- Engine condition
- Vehicle specification
- Existing exhaust components
- Intake modifications
- Engine calibration
- Fuel quality
- Ambient conditions
- Testing equipment and procedure
Why Upgrading Matters:
The Fabspeed Primary Muffler Bypass Pipe is primarily a performance, sound and weight-saving upgrade.
The original centre muffler does not need to have failed before the bypass pipe can be installed.
Reasons for upgrading include:
- Approx. 25 lb rear weight reduction
- Reduced exhaust restriction
- Improved exhaust flow
- Improved throttle response
- Increased horsepower potential
- More aggressive flat-six sound
- Carrera Cup-inspired configuration
- T304L stainless-steel construction
- Straightforward bolt-on installation
It provides a useful option for owners who want a noticeably sportier exhaust without deleting the catalytic converter.

- Porsche 95B.1 Macan Petrol 2.0L (237Bhp) 2014-18
Fabspeed Motorsport USA's engineering design staff designed Ultra High-flow, HJS German Imported 200 CPSI extra large direct bolt-on replacement for the bulky & restrictive factory Porsche Macan 2.0L 4 Cylinder catalytic converter.
The Porsche Macan is Porsche Ag's most popular high volume car in terms of sales. The Porsche Macan is a true drivers car and the Macan truly and really wakes up with a Fabspeed HJS German 200 cell catalytic converter.
Fabspeed engineering immediately focused on developing high performance Ultra Highflow replacement catalytic converters as a direct replacement bolt-on for the restrictive OEM Porsche 700 cell ceramic catalytic converters since Porsche loves to utilize 700 cell ceramic catalytic converters that restrict exhaust flow and limit performance and sound. Swapping out the OEM cats for a set of Fabspeed Sport Catalytic converters you can see improved performance without the worry of a check engine light. Our Sport Cats utilize German HJS 200 cell HD high-flow trimetallic catalytic converters for maximum exhaust gas flow and performance with zero check engine light worries.
FEATURES:
• Simple direct replacement ultra highflow genuine HJS German imported catalytic converter that replaces for the stock restrictive 8” long ceramic 700 cell OEM catalytic converter
• The largest HJS tri-metallic was deliberately chosen and utilized by Fabspeed Motorsport to maximize performance and durability

- Porsche 95B.1 Macan Petrol 2.0L (237Bhp) 2014-18
Unlock extra turbo sound, flat four aggression, and increased response with a bolt in catalytic converter delete downpipe for your Macan 2.0T.
• Fits all Porsche Macan 2.0T vehicles (2016-2018)
• All Soul Performance Products exhaust components are backed by the industry’s best Lifetime Warranty for both street and track use
DEVELOPMENT AND TESTING:
The Macan is rather quiet in factory format. Eliminating the restrictive factory catalytic converter adds to drivability and also unlocks the sweet sounds of the turbo with a major increase in snarling and crackles from the exhaust. The sound is aggressive without droning in the cabin. Smooth mandrel bent piping encourages better throttle response and a more exciting exhaust note. Easy to bolt in with no modifications required, this is a great, reversible solution to make your Macan more exciting.
CONSTRUCTION: Each downpipe is assembled out of mandrel bent, thick wall T304L stainless steel, then rigorously quality checked.
BOLT ON AND GO:
Every downpipe is rigorously quality-checked, tested in a fixture to guarantee fitment, and then foam packed to ensure it arrives in perfect condition.. New hardware is included.
CHECK ENGINE LIGHT?: This product may trigger a check engine light due to removal of the factory catalytic converter. We suggest a custom ECU tune to disable any check engine lights (for track use only).
LIFETIME WARRANTY: Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any issues or answer any questions that you may have.
NOTES
+ This product is not CARB certified and may not be legal for use on emissions controlled vehicles; intended for off road / competition use only due to removal of factory catalytic converters
+ Boost spikes can occur as a result of increasing the exhaust flow with a catless downpipe. We highly recommend an ECU tune to not only extract maximum power from this mod, but to have the best possible drivability as well
Please note: This item is not a stock product. It is a special order part and once ordered with us is not subject to cancellation or return unless proven not fit for purpose or defected.
