Description:
The Active Autowerke GESI G-Sport Ultra High Output catted downpipe for the BMW M3 E46 2001-2006 is engineered to unlock the full potential of your S54 engine without sacrificing daily drivability or OBD2 compliance.
Active Autowerke designed this downpipe to address one of the most significant restrictions in the factory exhaust system. By replacing the OEM unit with a 3.5-inch 304 stainless steel pipe paired with GESI G-Sport catalysts, exhaust gases exit faster, turbo spool improves, and power increases across the entire RPM range. The GESI catalyst is EPA-registered, rated 500-850hp, and backed by a 5-year / 50,000-mile warranty on the shell and tube ends. No check engine light, no compromises.
