Turner set out to amplify the E90 with a proper exhaust system. To accomplish this goal, the engineers at Turner increased flow, reduced weight by 45lb, and delivered an exhaust system that provides a noticeable bump in performance and captures the full unrestricted sound of the turbo inline-6 N54 or N55 engine. The increase in flow is gained from dual 2.5" titanium exhaust pipes that feed into the best designed mufflers on the market. Turner specifically designed the mufflers 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. Weight reduction is achieved by replacing the factory piping with lightweight Ti22 titanium and Ti22 mufflers for the most weight advantage possible. The best part of the full titanium 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 Titanium exhaust being the clear answer in your mission to find the best exhaust for your N54/N55 powered E90.
