Introducing the M5/M8 Primary Catted Downpipes - the ultimate upgrade for enhanced engine potential, increased power, and torque throughout the RPM range.
Constructed from top-quality T304 stainless steel, these downpipes are designed for longevity. Mandrel-bent for optimal flow, they feature smooth transitions to minimize turbulence and improve exhaust gas flow, resulting in noticeable power, torque gains, and a more aggressive exhaust note.
Installation is simple, requiring no cutting or welding. MAD M5/M8 Primary Downpipes are designed to bolt directly onto your BMW M5/M8s factory exhaust system and include all necessary hardware and gaskets for an easy installation.
