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.
These tuned resonators replace the factory resonator in section 2 of the exhaust. Supersprint also offers this section without any resonator at all. But if noise and volume is a strong consideration for you then using resonators is a good idea. If you were building a track car with headers and no cats then resonators will help keep noise levels low. This section is 309 stainless steel and 70mm diameter pipes (a little bigger than the factory size) so this piece will flow better and be a little louder than the factory resonator.
