New to our lineup of exceptional performance upgrades for your BMW, the Turner F8X M3/M4 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. Nobody will really even suspect your car even has an aftermarket exhaust system, as it sounds nearly identical to the factory system. 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 an axle-back or cat-back system! Give your M3/M4 the dual-purpose exhaust system that satisfies both your neighbors and your need for volume with the Turner Motorsport Valved Performance Exhaust System.

We set out to amplify the F80/F82 with a proper exhaust system. To accomplish this goal, our engineers at Turner increased flow and delivered an exhaust system that captures the full unrestricted sound of the twin turbo inline-6 S55 engine. The increase in flow was gained from dual 2.5" stainless exhaust pipes that feed into one of the best designed mufflers on the market. Our in-house engineers specifically designed the muffler with flow in mind to ensure that even with the exhaust valves closed, our Turner muffler flows better and sounds better than the stock muffler. The best part of the catback exhaust is the capability to control just how aggressive you want to your exhaust to sound, far beyond the point that the factory exhaust is able to perform. All of this plus the direct fitment and straight forward installation leads to the Turner Stainless exhaust being the clear answer in your mission to find the best exhaust for your S55 powered F80 or F82.

Transform the whole dynamic of your M3 or M4 with added performance, increased flow and not to mention the absolutely wicked sound you get from the upgraded Turner Performance Catback!
