Milltek Axle Back System with GT-115 Cerakote Black Trims for BMW G80 M3 and M3 Competition OPF - ECE Approved - SSXBM1170

Unlock the sound and style your BMW G80 M3 or M3 Competition deserves with the Milltek axle back exhaust system, part number SSXBM1170. This ECE approved rear section is engineered specifically for OPF and GPF equipped cars and features stunning GT-115 Cerakote Black tips for a stealth, motorsport-inspired finish. Expect a deeper, crisper, sportier exhaust note under load while remaining refined on the motorway with no unwanted NVH, drone or cabin resonance.

Every Milltek system is designed, developed and hand-finished in the UK using aerospace grade type 304 non-magnetic stainless steel. Mandrel-bent pipework maintains constant radius bends for optimised gas flow, and the carefully enlarged bore over stock helps performance without sacrificing mid-range torque. This is a premium, bolt-on axle back upgrade that elevates sound and aesthetics while maintaining everyday usability and ECE compliance.
