Information
Valvetronic GT3 Muffler Conversion Kit.
Porsche Boxster Cayman owners have requested a conversion kit that allows the installation of a Porsche OEM 991 GT3 center muffler onto their cars. Fabspeed Motorsport listened and designed in CAD and built inhouse a lightweight installation kit that allows any 6 speed Porsche 981 GT4 or Spyder owner to install an OEM GT3 center muffler (A PDK version will also be available once we are able to test fitment). This kit also allows the installation of a Fabspeed 991 GT3 Center Muffler Bypass Pipe or 991 GT3 Center Mini Maxflo Performance Exhaust onto your 981 GT4/Spyder.
The system consists of 2.5" 63.5mm CNC mandrel bent one piece Left and Right side over axle pipes and clamps. Then a set of valved side muffler inlet Y-pipes that retain the factory PSE valved exhaust functionality. The valves are OEM Porsche GT3 HELICAL vacuum-actuated exhaust valves that are imported from the U.K. We use our FLOW Waterjet to cut a CAD designed, lightweight, stainless steel mounting bracket to hold the muffler; hardware for installation is included. This and the Factory Porsche muffler band straps hold everything in place. For tips, you can use the factory 991 GT3 tips or you can order our custom exhaust tip mount with any choice of our signature tips.
SOUND: Enjoy the characteristic sound of a factory Porsche engineered exhaust but with a nice increase in volume! With PSE off (valves closed), the exhaust is still tame and livable in the cabin. However, with PSE on (valves open) hear that flat 6 howl up to redline! The larger over axle pipes that are included also contribute to the overall louder tone.
POWER: The 991 GT3 muffler was designed by Porsche to support 475 HP, because of this it flows a lot better than the 981 GT4 muffler that was only designed for 385 HP. We expect this increase in flow, helped by our larger over axle pipes and muffler inlets, to give a nice HP increase.

Fabspeed Header Muffler Kit WITH Heat Exchange
Fits : all Porsche 993 Carrera vehicles 1994-1998 - 3.6L / 3.8L and engines
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.

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.

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.
