Scorpion Exhausts De-Cat Downpipe (F20/F21 M135i)

£231.75 £208.57

As the official technical partner to the Airwaves BMW BTCC team, Scorpion knows exactly how to extract the best performance from high performance BMW engines.

These Scorpion F20/F21 M135i de-cat downpipes optimise exhaust flow by replacing the highly-restrictive factory catalytic converter, and also adds to the aural experience. This is one of the best upgrades you can make to allow the N55 engine to truly perform. Please note that as they replace the primary catalytic converter, these can result in MOT and emissions issues, and mapping to suit will be required to correct fuelling and avoid EML light.

These pipes bolt directly to the OEM system and use factory mounting locations. Combine with Scorpion M135i Half-System for a full turbo-back setup.
