Take full control of your Porsche’s exhaust system with the Valvetronic Designs Porsche OEM Exhaust Valve Controller—a true plug-and-play solution engineered for Porsche models equipped with vacuum-actuated exhaust valves. This controller gives you the power to open or close your exhaust valves on demand, even on models that feature factory valves but lack an OEM control button. Designed for enthusiasts seeking customizable sound, improved flexibility, and OEM-style functionality, this controller transforms your driving experience without requiring any performance modifications.

Perfect for vehicles such as the 991.1 Carrera S, this system allows you to unleash a more aggressive exhaust note or maintain a quiet, refined tone with complete driver-controlled flexibility. The installation is fully reversible, requiring no cutting, splicing, or permanent alterations to the car. For enthusiasts who want enhanced control, clarified sound character, and simple operation, this controller offers an ideal upgrade.

Due to varying vacuum solenoid suppliers for Porsche exhaust systems, some vehicles may require reversing polarity on the controller’s power and ground wires. This is a simple adjustment and ensures full compatibility across diverse Porsche platforms. Models such as the 991.1+ Carrera and 981+ Cayman/Boxster may require tapping into an external power source, but once installed, the controller integrates seamlessly and performs flawlessly.
