Akrapovic BMW X5M/X6M (F85/F86) Sound Kit

This easy-to-use optional extra gives the driver the opportunity to switch between dual-mode settings for either a sporty sound between the deeper and higher frequencies, or the more regular Akrapovič sound. It works by fully controlling the opening and closing of the exhaust valves simply by pushing a button on the Sound Remote Controller or via the downloadable app.
