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.
