Designed specifically for the new BMW F80 and F82 M3/M4, Active Autowerke introduces their most innovative cat-back exhaust system to date. Over 30 years of constant development and refinement in exhaust designs has resulted in this newest addition to the M3/M4 collection.
 

Active Autowerks F8X rear exhaust has been specifically engineered to destroy the simply unflattering sound factory M4 and M3s are stuck with from the factory while also providing optimum flow and resonance for a great sporty tone. When paired with the Active Autowerk Mid-Pipe sections, this system has been known to provide one of the deepest sounds and best performance of any other system on the market.
