The Turner Motorsport F3x 335/435i valved axleback 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 axleback system differs from others on the market, including the factory system, that only utilizes one side of the exhaust system for either valve closed or valve open operation the Turner valved axleback utilizes both muffler exits for valve open and valve closed operation. Featuring beautiful 1.25mm thick, 80mm 304SS pipes with smooth mandrel bends, this axleback 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 an axleback exhaust system well done, boys!
