Wagner BMW B58 Catless Downpipe (M140i, M240i, 340i & 440i & more)

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.

DISCLAIMER

This item is not intended for use on the public road (track use ONLY) as it does not comply with UK emission standards.
