OP - Optional part
For vehicles with the base Mercedes-AMG exhaust system, which is then replaced by the Akrapovič Evolution Line system, the Valve Actuator Kit (P-HF985) is a mandatory upgrade.
If the Evolution Line system replaces the Mercedes-AMG performance exhaust system, the Valve Actuator Kit (P-HF985) is not required.
