Scorpion Exhausts Decat Downpipe - BMW M235i

These Scorpion F22 M235i de-cat downpipes optimise exhaust flow by replacing the highly-restrictive factory catalytic converter and also add 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.

• 100mm (4″) into 76mm (3″) piping

Please note this exhaust is designed for motorsport use only. You will not pass a UK emissions test or police road side check with this exhaust installed on the vehicle.
