Turner Motorsport - Stainless Valved Catback Exhaust - BMW G8X M3/M4 ^Sale

Turner's mission was to amplify the G80/G82 with a proper catback exhaust system. To accomplish this goal, our engineers increased flow and delivered an exhaust system that captures the full unrestricted sound of the sonorous twin turbo inline-6 S58 engine. The increase in flow was gained from smooth flow path dual 3.0" stainless exhaust pipes that feed into one of the best designed mufflers on the market. Our engineers specifically designed the muffler with flow in mind to ensure that even with the exhaust valves closed, our muffler flows better and sounds better than the stock muffler. The best part of our Turner catback 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 our valved exhaust being the clear answer in your mission to find the best exhaust for your S58 powered G80 or G82. 

The G80 took the world by storm by breaking the mold of BMW's standard design language. With the G80 and G82, a whole new generation of M car owners emerged. At first people were hesitant about the larger more distinguished front grilles, but after the shock was gone the true glory of BMW's newest M cars began to shine. The G80 M3 and G82 M4 are incredibly capable cars out of the box and Turner's large range of upgrades means the sky is the limit. Give your G80 or G82 the aggressive exhaust note that you wanted from the factory with Turner Motorsport's G80 G82 Stainless Valved Catback Exhaust.
