More than 34 years of continuous exhaust development and technical expertise are drawn upon to develop the ultimate Milltek Sport range of performance products. The Milltek SSXAU408 Exhaust is a fully polished T-304 stainless steel, CNC mandrel bent, full system. The Milltek exhaust begins after the factory catalytic converters and continues back to the front center muffler and rear center muffler and finally to the valved rear mufflers and quad titanium 100mm round tips. The Milltek exhaust improves power and response and gives a deeper more aggressive sound. The valves in the rear mufflers can be opened or closed with an included switch to change between a street and race sound level.
