Unlock the sound and style your BMW G82 M4 and M4 Competition deserves with the Milltek particulate filter-back axle back exhaust system featuring GT-115 polished trims. This UK-made performance exhaust is the perfect OPF and GPF back upgrade for 2020-on S58 3.0 Turbo models, delivering a sharper, sportier tone without drone, enhanced rear-end presence and standout polished tailpipes.
Every Milltek system is designed, developed and hand-finished in the UK using aerospace-grade type 304 non-magnetic stainless steel. The result is exceptional durability, resistance to discolouration and a premium finish that lasts. Mandrel-bent pipework maintains constant radius bends for optimised gasflow, while carefully selected bore sizes improve flow without sacrificing mid-range torque. Extensive acoustic development ensures a crisp, engaging exhaust note without NVH, drone or intrusive cabin resonance.
