SST Exhaust Flap / Valve Control for Porsche Cayenne S (Type 9YA / 9YB) 2019–2023 – Without Sports Exhaust System
Unlock the full potential of your Porsche Cayenne S with the SST Exhaust Flap / Valve Control, designed specifically for Type 9YA/9YB models (2019–2023) without the factory sports exhaust system. This German-engineered plug-and-play control unit gives you complete command over your exhaust flaps, allowing you to tailor your driving sound and performance at the push of a button.
Compatible with the standard exhaust system, the SST control unit enables you to open or close the exhaust valves on demand — providing a deep, aggressive tone for spirited driving, or a quieter, refined sound for everyday comfort.
