Every Milltek system is designed, developed and hand-finished here in the UK by time-served craftsmen, each one produced in aerospace grade type 304, non-magnetic stainless steel. This superior material is less susceptible to discolouration, lasts almost indefinitely and is used throughout the entire construction of our pipework, silencers and associated hardware.

Mandrel bending ensures constant radius bends for optimised gasflow, and bore diameters are carefully enlarged over stock to ensure ultimate performance without the loss of mid-range torque. All of the Milltek exhaust systems endure a comprehensive acoustic development process to deliver a tone that is sporty and crisp, without ever inducing NVH, drone or cabin resonance.
