Milltek - BMW G80/G81/G82 M3/M4 Back with Centre Resonator Bypass System

Transform your BMW M3/M4 G80/G81/G82 with the Milltek OPF/GPF Back Exhaust System. This system bypasses the center resonator to deliver an enhanced exhaust note, optimized flow, and aggressive styling, while retaining compatibility with your car’s GPF setup.

Designed for late 2018+ vehicles equipped with Gasoline Particulate Filters (GPF), this system compensates for the sound-dampening effects of the filter, giving you a refined yet dynamic exhaust tone.
