The engineers at Akrapovic have retained the dual-mode exhaust flap control from the original system. This allows the vehicle to have a more civilized, but deeper than stock sound at low speed. However, at higher RPM (or when selecting the S mode on the gearshift) the muffler is bypassed, creating a deep and sporty sound much more in keeping with the personality of the car.

The tailpipes are the most visible part of the exhaust system, and that’s why they dedicate particular attention to them at Akrapovič. In order to satisfy the most discriminating tastes, they’ve created handcrafted carbon fiber tail pipes. To make their tail pipes stand out from the rest even more, in addition to selecting the finest materials, they also made them larger. This gives you car an even more dynamic look.
