Fabspeed RSR Header Muffler Bypass Straight Pipes 993 RSR Factory Race Car Style. 

The Fabspeed Porsche 993 Carrera RSR Header Muffler Bypass Straight Pipes are a performance exhaust upgrade designed to deliver an uncompromising motorsport-inspired exhaust note from the iconic air-cooled Porsche 911 Carrera (993).

Fits:

• Porsche 993 (911) C2 1994-97
• Porsche 993 (911) C4 1994-97  

Developed as an optional upgrade for the Fabspeed Maxflo RSR Header/Muffler Kit, these straight pipes replace the existing Fabspeed centre muffler or X-pipe, allowing exhaust gases to pass through a direct, minimally silenced exhaust path.

Inspired by the aggressive sound and lightweight exhaust arrangements associated with Porsche's factory 993 RSR racing cars, this upgrade is intended for drivers who want to experience a significantly louder and more visceral exhaust character.

Manufactured in-house by Fabspeed Motorsport from high-quality T304L stainless steel, the bypass pipes combine durable construction with a motorsport-focused design.

Unlike a conventional road exhaust system, which uses mufflers and resonators to reduce noise, these straight pipes remove the sound-reducing component from the compatible Fabspeed RSR exhaust arrangement.

The result is a dramatically louder, sharper and more aggressive exhaust note that emphasises the mechanical character of Porsche's naturally aspirated air-cooled flat-six engine.

The design also eliminates the weight associated with the existing muffler or X-pipe section, providing a lighter exhaust configuration.

The pipes connect directly to Fabspeed's RSR equal-length headers, including compatible header versions with or without cabin heating provisions.

Installation uses the existing aerospace-style V-band clamping arrangement, allowing the straight pipes to be exchanged for the compatible Fabspeed muffler or X-pipe without permanent modification to the headers.

Fabspeed also highlights the ability to return to a quieter exhaust configuration relatively quickly, making the system attractive to enthusiasts who alternate between circuit events and other permitted vehicle uses.

These bypass pipes are particularly suited to track-focused Porsche 993 Carrera builds, motorsport-inspired restorations and drivers seeking an authentic RSR-style exhaust experience.

What This Product Does:
The Fabspeed RSR Muffler Bypass Straight Pipes replace the muffler or X-pipe section of a compatible Fabspeed RSR exhaust system.

Their primary functions include:

• Bypass the Exhaust Muffler: Remove the sound-reducing centre section from the compatible Fabspeed Maxflo RSR system.
• Create an Aggressive RSR-Style Exhaust Note: Produce a significantly louder sound inspired by Porsche's air-cooled RSR racing cars.
• Provide a Direct Exhaust Flow Path: Allow exhaust gases to travel through straight stainless steel pipes rather than the existing muffler or X-pipe.
• Reduce Exhaust System Weight: Eliminate the mass of the removed centre muffler or X-pipe assembly.
• Complement Equal-Length RSR Headers: Connect directly to compatible Fabspeed RSR headers.

Fabspeed Long Tube Race Headers.

The Fabspeed Long Tube Race Headers are a competition-focused exhaust upgrade developed for naturally aspirated Porsche 911 GT3, GT3 RS and 911 R models of the 991 generation.

Fits:

• Porsche 991.1 GT3 3.8L (475 Bhp) 2014-16
• Porsche 991.2 GT3 4.0L (500 Bhp) 2017-19  

Designed for circuit, motorsport and off-road applications, the system replaces the factory catalytic-converter-equipped headers with a carefully developed long-tube header arrangement engineered to improve exhaust scavenging, reduce restriction and maximise the breathing potential of Porsche's high-revving flat-six engine.

Fabspeed developed the system in conjunction with Burns Stainless, using motorsport-derived high-velocity merge collectors and long primary tubes to improve the way exhaust pulses leave each cylinder and combine within the exhaust system.

The headers are manufactured from T321 stainless steel, CNC mandrel bent and hand TIG welded with back-purging. T321 is particularly well suited to high-temperature motorsport exhaust applications because of its excellent resistance to repeated thermal cycling.

Fabspeed's current product listing quotes performance gains of approximately:

+19 HP

+13 lb-ft of torque

These are manufacturer-listed figures from specific testing and should not be regarded as guaranteed gains for every vehicle.

Because the system removes the original catalytic converters, it is specifically intended for closed-course competition and off-road use rather than public-road use.

What This Product Does:
The Long Tube Race Headers replace the original Porsche exhaust manifolds and catalytic-converter assemblies with a freer-flowing competition header system.

They are designed to:

• Improve exhaust gas evacuation from each cylinder.
• Reduce exhaust restriction.
• Improve exhaust pulse scavenging.
• Support increased horsepower and torque.
• Improve throttle response.
• Enhance high-RPM breathing.
• Complement the high-revving character of the GT3 engine.
• Produce a significantly more aggressive exhaust note.
• Reduce catalyst-related exhaust restriction.
• Support additional competition engine and exhaust modifications.

Symptoms Of Wear Or Failure:
Race headers are exposed to severe temperature and vibration.

Possible symptoms of deterioration include:

• Ticking noises from the exhaust.
• Blowing noises during acceleration.
• Visible exhaust leaks.
• Soot around welds or flanges.
• Cracked primary tubes.
• Cracked welds.
• Damaged collectors.
• Loose slip joints.
• Increased exhaust smell.
• Metallic rattling.
• Exhaust vibration.
• Reduced performance.
• Exhaust noise changing unexpectedly.

Why Replacement Matters:
Replacing cracked or damaged headers helps restore:

• Correct exhaust sealing.
• Intended exhaust scavenging.
• Smooth exhaust flow.
• Proper collector operation.
• Safe containment of hot exhaust gases.
• Structural integrity.
• Consistent engine performance.

For track-driven cars, header condition should be checked regularly because operating temperatures and mechanical loads can be considerably greater than during normal road driving.

Fabspeed RSR Muffler Bypass Pipes.

The Fabspeed RSR Muffler Bypass Pipes are a motorsport-inspired exhaust upgrade for Porsche 911 964 Carrera models already equipped with the Fabspeed Maxflo RSR Header/Muffler Kit in its Non-Sport-Cat configuration.

Fits:

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

Designed to replace the Fabspeed mufflers with direct stainless-steel outlet pipes, they create a considerably less silenced exhaust path and give the air-cooled flat-six a much louder, more aggressive race-car character.

Rather than routing exhaust gases through conventional mufflers, the bypass pipes connect directly to the existing Fabspeed RSR headers. This reduces rear exhaust restriction and removes much of the sound attenuation provided by the mufflers.

The result is a raw, highly audible air-cooled exhaust note inspired by Porsche competition cars and intended primarily for drivers seeking maximum sound and a more direct motorsport experience.

Manufactured in-house by Fabspeed from T304L stainless steel, the pipes are designed for durability, heat resistance and straightforward bolt-on installation.

What This Product Does:
The RSR Muffler Bypass Pipes replace the muffler sections of the compatible Fabspeed exhaust with direct outlet pipes.
