Build quality you can trust
Every Milltek system is designed, developed and hand finished in the UK by time served craftsmen. Type 304 non magnetic stainless steel is used throughout the pipework, silencers and hardware for long lasting durability and consistent appearance. Mandrel bending delivers smooth, constant radius bends for superior exhaust gas flow. Enlarged bore sizing is carefully engineered to maximise performance without sacrificing mid range torque.
Sound you will love, without the drone
Each Milltek BMW M8 exhaust goes through extensive acoustic tuning. The result is a deeper, more characterful V8 soundtrack with a crisp top end, and controlled volume inside the cabin. The valved rear silencer bypass gives you the flexibility to enjoy a louder, more motorsport inspired note, then return to a more civilised tone for daily driving.
