Because of packaging requirements, the EVO system is split into two codes. Both part numbers (MTP-ME/T/2H/1 or MTP-ME/T/3H and E-ME/T/3) must be ordered.
If the Evolution Line system replaces the Mercedes-AMG performance exhaust, the Valve Actuator Kit (P-HF985) is not needed and the valves can be controlled from the cabin; the Akrapovič Sound Kit (P-HF949) is optional. If the car has the basic Mercedes-AMG exhaust instead of a performance exhaust, the Valve Actuator Kit (P-HF985) is mandatory and the Sound Kit (P-HF949) is highly recommended for complete sound control.
