Active Autowerke Catted Downpipes - F10/F12 M5/M6 S63
The Active Autowerke Signature GESI Catted Downpipes offer the perfect balance of raw performance and street-legal refinement. Unlike "catless" alternatives that cause unpleasant fuel odors and dashboard error lights, this system utilizes EPA-registered GESI high-flow catalytic converters. These proprietary converters use precious metal loading technology to significantly reduce emissions, ensuring your BMW remains OBD2 compliant and "Check Engine Light" free.
Designed as a direct bolt-on replacement for F-Chassis BMW X5M, X6M, and 550i/650i models, these downpipes feature cast upper stainless steel V-bands for a factory-perfect seal. Whether you are cruising or under wide-open throttle, the system maintains a sophisticated exhaust note while safely protecting both passengers and the environment from harmful fumes.
