Description
Enhance your BMW F80 M3 and F82 M4 with the Active Autowerke Mid Pipe, designed for superior performance and sound refinement. Active Autowerke, with over 41 years of experience in BMW performance engineering, has created this mid pipe to significantly reduce back pressure, optimize exhaust flow, and eliminate the restrictive nature of the factory mid pipe. The result is improved performance, increased horsepower, torque gains, and a deeper, more aggressive exhaust note.
The F8X Mid Pipe eliminates the "weed-eater" sound often complained about in the stock exhaust by utilizing a single-pipe design and an innovative 3.5" oval pipe to maintain optimal ground clearance. This design not only enhances the sound but also maximizes power output, making it an essential upgrade for any BMW enthusiast seeking a refined driving experience.

Performance Mid Pipe Redesign: The factory F8X exhaust system includes two silencers and a small internal crossover to dampen noise, which also restricts exhaust flow and amplifies the uneven turbocharger sound. The Active Autowerke Mid Pipe addresses these issues with a single-pipe design that improves flow and produces a more harmonious sound expected from an M performance vehicle. This design also results in a lighter exhaust system, contributing to improved performance.
Note: The Active Autowerke Full Exhaust System is recommended for, but not limited to, off-road or racing applications.
