The Akrapovic Cat-back Titanium exhaust system for the BMW F90 M5 is designed for drivers who demand more power and less weight. In addition to weight reduction and a power gain, one of the tasks of the Akrapovic team was also to make the sound of the M5 become music to ones ears. An optional wireless "dualmode" exhaust flap control allows the vehicle to have a more civilized, but deeper than stock sound at low speed. However, when the exhaust flap is opened the muffler is bypassed, creating a deep and sporty sound much more in keeping with the personality of the car.

Power gains come in at +11.3hp (at 5700 RPM) and 21.3Nm (at 2300 RPM) with just the exhaust alone, and a total weight savings of 20.8 lbs! That is a 32.6% overall reduced difference in weight from stock.

Not for sale outside the US or Canada.
