BMW Exhaust Parts, Mufflers & Catalytic Converters for BMW F82 M4 S55 3.0L

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!
