For over 30 years, Active Autowerke has set the standard for BMW performance. The F95 X5M / F96 X6M GESI High-Flow Downpipes carry that legacy forward, engineered to unlock power, cut radiant heat, and free the S63TU from the most restrictive part of its factory exhaust.
Crafted in-house in Miami, Florida from premium 304 stainless steel, each downpipe is TIG-welded for strength and precision fitment. A factory-matched 3.5” V-band inlet flows through a high-efficiency, mandrel-bent body for maximum exhaust velocity and quicker turbo spool. The design retains the OEM O2 sensor heat shield for a clean, stock-like engine bay.
Featuring 4.5” GESI Ultra High Output (UHO) catalytic converters, these downpipes offer massive flow gains while staying 49-state EPA compliant and OBD2 safe, all without triggering a CEL. Expect sharper throttle response, a deeper tone, and consistent performance from street to track.
