Description
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.
One of the keys to gaining power in any turbo engine is from reducing restrictions. By replacing the factory catalytic converter with a freer-flowing piece you are picking up additional power and still keeping the exhaust gases clean. This downpipe for the B48 engine is a direct replacement for the stock downpipe and includes a metallic catalytic converter. Supersprint dyno testing revealed a 15hp/10ft-lbs increase using this downpipe and the rest of their exhaust system.
