Wagner Tuning BMW B58 200CPSI Performance Downpipe is a stainless steel sports cat designed to increase airflow whilst complying with on-road emissions regulations. Designed specifically for the B58 engine this downpipe reduces back pressure which improves throttle response and low-mid range torque. The vehicle's exhaust note also benefits as this sports cat really allows the B58 engine to sing.
