Active Autowerke BMW S58 F97 F98 X3M X4M Downpipes with GESI CATs
Active Autowerke downpipes for the BMW S58 engine in the F97 X3M and F98 X4M are built with GESI catalytic converters, providing a direct replacement for the factory downpipes. The GESI CATs are designed to handle the increased exhaust flow of the S58 twin-turbo inline-six while maintaining emissions compliance.
These downpipes are engineered specifically for the F97 X3M and F98 X4M chassis, ensuring a precise fit with the factory exhaust system. The construction uses high-quality stainless steel for durability and resistance to the extreme temperatures of turbocharged exhaust gases.
