Transform your BMW M5 F90 with the Milltek Cat-back Exhaust System, the go-to performance exhaust upgrade for M5 and M5 Competition owners who want more sound, more flow and race car presence. This cat back system includes an OPF GPF bypass and comes finished with stealthy Cerakote Black GT-100 tailpipes that look as good as they perform.
Hand finished in the UK, every Milltek system is built from aerospace grade type 304 non-magnetic stainless steel for exceptional durability and corrosion resistance. Precision mandrel bending maintains a constant radius for optimised gas flow, while the enlarged bore is engineered to unlock performance without sacrificing mid-range response. Milltek’s acoustic development delivers a deep, motorsport-inspired tone that is crisp and aggressive without intrusive cabin drone.
