Milltek Sport exhausts are produced in high quality type 304 aircraft grade stainless steel. This material is anti-magnetic (other manufacturers' stainless steel may not be) and is less susceptible to discoloration. This quality of stainless steel is used on all pipe work and the total construction of the silencer. Mandrel bending ensures full flow bends for better gas flow and Milltek Sport exhaust systems are increased in bore to ensure ultimate performance without the loss of mid-range torque. All Milltek Sport exhausts are designed, developed and manufactured in-house in the UK.
