Wagner Tuning BMW B58 Catless Downpipe removes the factory catalytic convertor for increased performance and tuning potential. Decatting your B58 engine dramatically reduces back pressure in the OEM exhaust system - improving throttle response, torque and noise. This is an essential upgrade for those looking to tune their B58-powered BMW as the factory downpipe will severely restrict performance gains.
