Milltek Sport 102mm Non-Res Single Midpipe | BMW G8X M3/M4

Engineered strictly for raw track performance and unrestricted exhaust gas velocity. The Milltek Sport Midpipe scales flow up to a massive 102mm (4-inch) main single-pipe section, completely eliminating the restrictive secondary factory catalytic converters and center resonators. Featuring an investment-merged, non-resonated crossover architecture, it maximizes twin-turbo exhaust scavenge cycles to rapidly pull heat away from the turbos. This delivers a violently loud, metallic, screaming motorsport frequency that turns your G80 M3 or G82 M4 into a true Track Rat. High-strength construction built to withstand constant track abuse.
