Milltek Large-bore Downpipe for BMW 1 Series M140i 3 & 5 Door (F20 & F21 LCI, Non-OPF) (2015-2018) – Improved Turbo Flow
This is Milltek's large-bore downpipe for the BMW 2 Series M240i Coupe (F22 LCI, Non-OPF & Non-xDrive). It replaces the factory downpipe with a larger-bore pipe for improved flow at one of the most restrictive points in the system. Check the specification below to see whether this particular version retains a catalyst or removes it.
If the catalyst has been removed, this is intended for off-road and competition use only and the car won't be legal for road use fitted with it. Check the specification below for this system's catalyst and approval status.
