Milltek Axle Back Exhaust for BMW 2 Series M2 Coupe (G87 S58 OPF/GPF Models) (2023 onwards) – Sportier Note, Simple Fitment
This is Milltek's axle-back exhaust for the BMW 2 Series M2 Coupe (G87 S58 OPF/GPF Models). It replaces the exhaust from the rear axle back, the shortest section Milltek offers on this platform, swapping the factory tail section for wider-bore pipework and a silencer tuned for a sportier note. Everything ahead of the rear axle, including the mid-pipe, stays standard. It's offered in 5 tailpipe finishes, so you can pick the setup that suits how the car's used.
It's the option for a subtle, tail-end-only change in sound and look, rather than the fuller transformation of a cat-back or front-pipe-back system.
