When deciding on the right exhaust the hardest part is feeling confident in the best sound mixed with increased performance, this really leaves you to guess based on reputation. Fortunately, Supersprint has the reputation covered when it comes to BMW exhausts. For over 60 years their goal has always been designing and building the highest quality exhaust available. This has been achieved through extensive testing using real race teams to get the best feedback there is to offer, from the ones who demand the best everyday. Extensive dyno testing, high quality materials, and race team feedback are what allow Supersprint to extract the power from your engine, not just the noise.
This rear muffler is designed to fit with the stock US catalytic converter or the Supersprint center resonator. It's more open and freer-flowing than the stock exhaust or the Supersprint muffler. With less resistance the engine can move exhaust gasses easier which frees up horsepower and torque. Note: this exhaust is considerably louder than the stock exhaust - if used on a street car, check with local authorities for sound limits.
