Akrapovič sound control kit, manufacturer part number P-HF1199, for PORSCHE 536 Cayenne (E3).

Further control over the sound of the Evolution Line (Titanium) exhaust system can be achieved by installing the optional  Akrapovič Sound Kit . This gives the occupants of the car the option to regulate the exhaust tone by switching between the quiet mode and a sportier sound. This is facilitated through the use of a  Sound Remote Controller  or the  smartphone app  (for iOS and Android), which regulates the valves to drive the actuators that open or close them through the use of a receiver in the system. When fitted with the optional Akrapovič Sound Kit, ECE type approval is no longer valid. SCHEMATIC NEW VERSION USER MANUAL INSTALLATION INSTRUCTIONS
