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.
Constructed from high-grade lightweight titanium with two pairs of titanium / carbon-fiber tailpipes and featuring exhaust valves with housings cast in the in-house foundry, the Akrapovič exhaust system for X3 M/ Competition is a stunning design that combines performance with an incredible soundtrack and huge visual appeal. The sound has been tuned to ideally suit the in-line six-cylinder turbo engine, delivering an increase in the volume sensation, which provides exciting acoustic feedback when shifting through the gears. Any unwanted drone is eliminated.
This axle-back exhaust system is manufactured entirely from titanium. This makes this system ideal for cutting weight while being structurally stronger than the OE exhaust system.
