The Fabspeed Porsche 964 Carrera RSR Header Muffler Kit is a comprehensive performance exhaust system designed to transform the exhaust flow, sound and character of the air-cooled Porsche 964.
Fits:
- Porsche 964 (911) C2 1989-94
- Porsche 964 (911) C4 1989-94
Inspired by Porsche RSR motorsport exhaust architecture, the system replaces key restrictive factory exhaust components with equal-length RSR-style headers, high-velocity 3-into-1 merge collectors and a dual-outlet performance muffler system.
The result is a freer-flowing exhaust path designed to improve engine breathing, increase horsepower and torque potential, reduce weight and deliver a significantly louder and more aggressive air-cooled flat-six exhaust note.
What This Product Does:
The exhaust system has the important job of carrying combustion gases away from the engine while controlling exhaust flow, noise and, depending on the configuration, emissions.
On a performance engine, the design of the headers, collectors and mufflers can significantly influence how efficiently exhaust gases leave the cylinders.
The Fabspeed RSR Header Muffler Kit replaces several major factory exhaust components with a performance-oriented system designed to:
- Improve exhaust-gas flow
- Reduce exhaust restriction
- Improve exhaust scavenging
- Improve engine breathing
- Increase horsepower and torque potential
- Improve throttle response
- Reduce exhaust-system weight
- Produce a louder, more aggressive exhaust note
- Create an RSR-inspired appearance and character
Performance Benefits:
Fabspeed reports substantial performance improvements from the RSR Header Muffler Kit.
The manufacturer's current published figures vary between sections of its product listing, with performance gains quoted in the region of approximately:
Horsepower: +24 to +29 HP
Torque: +21 to +24 ft-lb
Weight Reduction: Up to approximately 38 lb depending on configuration
These figures are manufacturer-reported and should not be interpreted as guaranteed results for every Porsche 964.
Actual results will vary depending on:
- Engine condition
- Vehicle specification
- Exhaust configuration
- Sport Cat or non-Sport Cat configuration
- Intake modifications
- Engine calibration
- Fuel quality
- Ambient conditions
- Testing equipment and procedure
Why Upgrading Matters:
This system is primarily a performance upgrade, rather than a routine replacement component.
The factory exhaust does not need to have failed before the kit can be installed.
Reasons for upgrading include:
- Equal-length RSR-style headers
- High-velocity 3-into-1 merge collectors
- Improved exhaust flow
- Improved exhaust scavenging
- Increased horsepower and torque potential
- Improved throttle response
- Significant weight reduction
- Loud and aggressive flat-six sound
- RSR-inspired appearance
- T304L stainless-steel construction
- Optional heat-exchange configuration
- Optional Sport CatsChoice of exhaust outlets
It is particularly suited to enthusiast, performance and RSR-inspired Porsche 964 builds where increased sound, reduced weight and improved exhaust efficiency are priorities.
