The Akrapovic Sound Kit allows the driver to easily adjust the sound of the exhaust from inside the cars cockpit. Using the latest innovative technology and working with the cars own electronics, the Akrapovic Sound Kit provides different sound characteristics through the control of the active X-connection built into this superb Evolution Line (Titanium) system.

For cars equipped with the base Mercedes-AMG exhaust system with no exhaust system button inside the cabin the Akrapovic Sound Kit (P-HF949) is a highly recommended upgrade to take complete control over the exhaust sounds. If the car is already equipped with exhaust valve button inside the cabin, the sound kit is not needed.
