The Turner Motorsport F3x 335/435i valved catback exhaust allows you to blend in with the valves closed, or let your N55 sing with the valves open - the choice is in your hands. This valved catback system differs from others on the market, including the factory system, that only utilize one side of the exhaust system for either valve closed or valve open operation - the Turner valved catback utilizes both muffler exits for valve open and valve closed operation. Featuring beautiful 1.25mm thick, 80mm 304SS pipes with smooth mandrel bends, this catback is as pleasing to the eyes as it is to the ears. We're proud of our friends at Turner Motorsport for doing the F30 335i the justice it deserves from a catback exhaust system - well done, boys!
