This Milltek twin OPF/GPF bypass for the G80/G81 M3 replaces both factory particulate filters with left and right bypass pipes, joined by Milltek's Z pipe, for a freer-flowing exhaust and a stronger S58 note.
It fits to the original BMW downpipes and is available to suit either the OE axle-back or a Milltek Sport axle-back system.
Please note: this is a race product intended for off-road/motorsport use only. Removing the OPF/GPF is not road legal in the UK, and the car may need an ECU remap to run without fault codes.
