Turner Motorsport F80 F82 M3/M4 Stainless Performance Cat-Back Exhaust - Valved

Turner set out to amplify the F80/F82 with a proper exhaust system. To accomplish this goal, the 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. Turner specifically designed the muffler with flow in mind to ensure that even with the exhaust valves closed, the 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 Turner Stainless exhaust being the clear answer in your mission to find the best exhaust for your S55 powered F80 or F82.
