Miltek Sport Exhaust systems - Over 20 years of continuous exhaust development and technical expertise are drawn upon to develop the ultimate Milltek Sport Exhaust System.Whether it be a Cat Back Exhaust or a Full Turbo Back System they are feature the best in Stainless Steel technology available.

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 discolouration.
