Up the aggression and drop weight while unleashing the visceral tones of the N55 engine
There are loud exhausts, there are great sounding exhausts. When you have a loud AND great sounding system....M235i OH MY! The N55 has a great voice to match the power it produces, and we wanted to let it sing. Our Muffler Bypass Exhaust System deletes the rear muffler, shedding 14 lbs in the process. This is an exhaust for those who like it aggressive. Expect an intoxicating and menacing barrage of pops and crackles upon deceleration. In cabin tone is very reasonable, with our Sport Cat Downpipe installed we would have no qualms daily driving it at all.
FEATURES:
All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty
NOTE: Installation requires cutting the factory exhaust near a factory break point. Everything required for installation is included. The Fabspeed system installs quickly over the factory piping using the included Torca clamp. Reinstallation of the factory rear muffler (for our friends with leased vehicles) is quick and easy!
