Fabspeed's RSR Header Muffler Kit is a full exhaust system developed for track use provides an aggressive exhaust note while adding horsepower, torque, and throttle response; available as single or dual outlet and with or without heat exchange. Works great on street cars too. This Header/Muffler kit is built from the ground up to optimize performance for the Porsche 993 Carrera. Beyond just improving horsepower, torque, and throttle response, this package will also reduce the overall weight of your car by 43 pounds, which improves handling and acceleration.
SOUND:
This kit is designed specifically for use on the track, but works well for street drivers who want an aggressive and track-inspired exhaust note.
POWER:
We developed every inch of it to bring out the aggressive performance that the Carrera is capable of. On our dyno we saw gains of 29whp and 25ft/lbs of tq.
FEATURES:
• Loud and aggressive cup car sound
• 1.75" / 45mm Header tubes, 26" long
• This system can be ordered with single or double outlets
• Maintain your factory in-cabin heat with the optional heat exchange on the headers
• Saves 43lbs from the rear of the vehicle with heat exchange option, and saves 47lbs without heat exchange option
• Constructed from mandrel bent T304L stainless steel
• Simple DIY bolt-on installation, no cutting or welding required
• All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty
NOTE:
This package can be purchased with a heat exchange on the headers that will help maintain the factory in-cabin heat. Without the exchange system, you'll save an additional 4 lbs, for a total of 47 pounds of weight reduction.
PURCHASE DISCLAIMER: Fabspeed Motorsport does not condone the use of emission defeat devices for any vehicles used on public streets or roadways. Fabspeed Motorsport will not tamper, remove, disable, or bypass emissions equipment on a motor vehicle in accordance with 40 CFR Section 86.1854.12(a)(3), Clean Air Act 40 CFR 1068.101(b). This includes software, known as tunes, that reprogram a motor vehicles electronic control module to alter engine performance and enable the removal of filters, catalysts, and other critical emissions controls.
Please note: This is a special-order item manufactured to order. In some cases, please allow 4 – 5 weeks for the delivery. Special order items cannot be cancelled from this supplier once your order has been placed.
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.

The Fabspeed Competition Race Exhaust System is an extreme lightweight, maximum-flow exhaust solution developed for the twin-turbocharged Porsche 911 993 Turbo, Turbo S and GT2.
Fits:
- Porsche 993 (911) TURBO 1994-96
- Porsche 993 (911) GT2 1994-97
- Porsche 993 (911) TURBO S 1994-97
Inspired by the exhaust layout and sound of the legendary Porsche Motorsport 993 GT2 and GT2 EVO race cars, the system replaces the heavy and restrictive factory rear exhaust arrangement with compact straight-through race outlets positioned directly after the twin turbochargers.
By dramatically shortening the exhaust path and eliminating the large factory silencer system, the Fabspeed Competition Race Exhaust reduces backpressure after the turbochargers, decreases rear-mounted weight and produces an exceptionally direct motorsport exhaust note.
The system is manufactured from high-quality 14–16 gauge T304L stainless steel using CNC mandrel-bent tubing for smooth exhaust flow and long-term durability under demanding competition conditions.
Fabspeed states that the system saves over 80 lb / 36.4 kg compared with the factory exhaust arrangement, removing substantial mass from the rearmost area of the vehicle.
Fabspeed also describes noticeably faster turbo response and cites a 40+ HP performance benefit in its detailed feature information. However, the current specification panel lists horsepower and torque figures as TBD, so a fixed power increase should not be regarded as guaranteed.
What This Product Does:
The Competition Race Exhaust replaces the standard rear exhaust arrangement with an extremely short and unrestricted exhaust path from the twin turbochargers.
It is designed to:
- Reduce exhaust backpressure.
- Improve exhaust gas evacuation after the turbochargers.
- Improve throttle response.
- Help the turbochargers respond more quickly.
- Support increased engine performance.
- Remove substantial rear-mounted weight.
- Produce an authentic GT2 / GT2 EVO-inspired race-car sound.
- Reduce exhaust-system complexity.
- Provide maximum-flow competition exhaust routing.
- Work with or without compatible factory-style exhaust tips.
Symptoms Of Wear Or Failure:
The system contains no conventional muffler internals to deteriorate, but the pipes, flanges and welded joints remain exposed to severe heat, vibration and engine movement.
Possible symptoms of deterioration include:
- Exhaust ticking.
- Blowing noises.
- Visible exhaust leaks.
- Black soot around joints.
- Cracked welds.
- Cracked tubing.
- Damaged flanges.
- Loose fasteners.
- Excessive movement.
- Metallic rattling.
- Dented or crushed tubing.
- Unexpected changes in exhaust sound.
- Increased exhaust fumes.
- Heat damage to surrounding components.
Why Replacement Matters:
Replacing a cracked, leaking or physically damaged Competition Race Exhaust helps restore:
- Correct exhaust sealing.
- Maximum-flow pipe geometry.
- Low post-turbo restriction.
- Proper alignment.
- Structural integrity.
- Safe containment of hot exhaust gases.
- Consistent turbo response.
- Correct competition exhaust sound.
Because the system operates immediately downstream of the turbochargers, maintaining its structural condition is particularly important.
