Scorpion Catless Downpipe - BMW M135i (F20) Pre-June 2013 - 76mm
For race use only. This is a catless part for off-road and competition vehicles. It has no catalytic converter and is not legal on a road-registered vehicle in Australia.
This Scorpion catalyst replacement swaps the factory downpipe and catalytic converter on early BMW M135i (F20) models for a 76mm (3") T304 stainless catless pipe. Removing the restrictive cat lowers back-pressure for quicker turbo response and a louder, sharper exhaust note. It connects to the OE exhaust or a Scorpion system.
Note: Pre-June 2013 builds only – later cars need the post-June 2013 version (SBMC067). Scorpion states this part removes a factory emissions control device and is for motorsport use only. Expect the engine management light to come on; Scorpion recommends a Stage 2 ECU remap. Installation by a professional is recommended.
