How It Works
Installed inline with the factory exhaust control unit, the CARGRAPHIC system adds custom valve logic based on drive mode and ESP button input. It enables more refined control of exhaust acoustics and integrates seamlessly into your car’s electronics—no remotes or extra modules required.
Additionally, it can memorize your engine Start/Stop setting, so you don't have to disable it every time.
