Built in Britain. Engineered to perform.
Every Milltek system is designed, developed and hand-finished in the UK by time-served craftsmen. Type 304 stainless steel is used throughout the pipework, silencers and associated hardware for exceptional longevity. Mandrel bending ensures constant radius bends, while enlarged bore diameters maximise performance potential. The result is a sharper throttle feel and a richer, more engaging exhaust note tailored for the BMW M5 F90 platform.
