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.
