New to our lineup of exceptional performance upgrades for your BMW, the Turner E9X 335i catback exhaust system is here to improve your driving experience with hearty exhaust notes and a noticeable bump in performance. Our Exhaust system Sports Mandrel bent dual 2.5” 304SS pipes with a nice brushed finish. Exhaust gases flow through efficient piping to High flow, valved, stainless steel mufflers. Under normal driving conditions, the vacuum controlled muffler valves stay closed, and the exhaust is quite unassuming.

But, when you open up the throttle, the vacuum controlled valves open up, and this exhaust gives your car a menacing growl. Designed to mount using the factory exhaust hangers, this exhaust is a bolt-on replacement for the OE version. To help reduce the time you spend installing the system, Accuseal slip-fit joints are included to make fitment as easy as possible. The Turner Motorsport full exhaust system includes a High flow, valved, stainless-steel muffler and is available as Cat-back system as well as a full turbo back system. Give your 335i the dual-purpose exhaust system that satisfies both your neighbors and your need for volume with the Turner Motorsport E9X 335i full exhaust system.
