Valve Controllers & Exhaust Flap Control Solutions
Our current Cargraphic range focuses on valve controller units for Porsche exhaust systems — allowing you to manually override your factory exhaust flaps for a more engaging driving experience.
These advanced control units are designed to:
- Give you full control of your Porsche’s exhaust valves, with options to keep them permanently open or allow automatic factory operation
- Improve exhaust sound and throttle feel
- Plug directly into your vehicle with OEM-style connectors
- Be installed and removed with no permanent modifications required
Whether you drive a Porsche 911 (992, 991, 997 etc.), Boxster/Cayman 718, or other Porsche models with factory exhaust valves, the Cargraphic valve controller delivers enhanced exhaust engagement and driver-focused control.
