If the Akrapovič Evolution Line system replaces the Mercedes-AMG performance exhaust system, the Valve Actuator Kit (P-HF985) is not needed. The valves on the exhaust can be controlled from the car cabin. The Akrapovič Sound Kit (P-HF949) can be purchased as an optional part.
If the car is not equipped with a performance exhaust but with the basic Mercedes-AMG exhaust system, then the Valve Actuator Kit (P-HF985) is mandatory. The Akrapovič Sound Kit (P-HF949) is also highly recommended for complete control over exhaust sound regulation.
Because of packaging requirements, the EVO system has been split into two codes. Please be aware that both part numbers (MTP-ME/T/2H/1 and E-ME/T/3) must be ordered.
