This system is constructed using lightweight race-proven materials, titanium for the muffler and link pipe section, and carbon fibre for two sets of newly designed, hand-crafted tailpipes, delivering a result that is over 41% lighter in comparison to the standard stock system. The Evolution Line (Titanium) has been produced with a valve Ð which has a housing cast in AkrapovicÕs own foundry Ð fitted outside the muffler. This design feature with perfect gas flow allows the sound to be tailored to deliver an Akrapovic aural effect. This creates a smooth, rich sound at normal cruising, with a deep and sporty tone when driving the Audi S3 more dynamically. Power is increased by 4 kW (5.4 hp) at 4,350 rpm, with a torque gain of 8.8 Nm at 3,900 rpm. These figures were measured on the Akrapovic dyno when tested against an Audi S3 with a standard stock exhaust. No remapping is required, giving it a plug-and-play capability, and an optional Akrapovic Sound Kit is also available to offer the driver greater control over the superb tones produced by the system. The exhaust system is ECE type approved for cars equipped with an Otto/gasoline particulate filter.
