Looking to get the most out of your G8x M3/M4? Fabspeed has the answer with our Turbo Back Exhaust Package. Starting with our Sport Cat Downpipes that feature high quality HJS catalytic converters. This guarantees the most exhaust flow, reliability, and sound. Then, we use our unique intermediate X-Pipe that features two X-Pipes for proper exhaust scavenging and sound balance. And finally our Valvetronic exhaust, which features Helical Valves from the U.K. that are plug and play with the factory valve controllers. This system is your ticket to bolt on sound and performance without any loss of functionality or CEL’s (Check engine lights).
