Akrapovic Sound Kit For 536.2 Porsche Cayenne / E-Hybrid / S E-Hybrid / Coupe

For vehicles with the base Porsche exhaust system, which is then replaced by the Akrapovič Evolution Line system, the Middle Valve Actuator Kit (P-HF1170) is a mandatory upgrade. If the Evolution Line system replaces the Porsche sports exhaust system, the Middle Valve Actuator Kit (P-HF1170) is not required.
