The optional Akrapovič Sound Kit enables owners of selected Akrapovič car exhausts to control the sound of the system from the cockpit of their vehicle. Using Akrapovič technology, drivers can easily switch between the quiet mode and a sportier sound. With the use of a receiver to drive the actuators that open or close the valves at the end of the exhaust system, drivers can use the Sound Remote Controller or the new smartphone app (for iOS and Android) to regulate the valves.

Akrapovič Sound Kit P-HF1177 is developed for use with Slip-On Line (Titanium) only. If upgrading the slip-on system with evolution link pipe, specially developed Akrapovič Sound Kit is already included within the evolution link pipe set.

With the use of the optional Akrapovič Sound Kit, the ECE type approval is no longer valid.
