Scorpion Exhausts De-Cat Downpipe for F40 M135i.

As a household name for aftermarket exhausts, Scorpion knows exactly how to extract the best performance from high performance BMW engines.

The Scorpion M135i De-Cat Downpipe optimises 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 B48 engine to truly perform. Please note that as this replaces the primary catalytic converter, this 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.

Please note that removal of emissions equipment is not MOT compliant and so these parts are for off-road use only.
