For those looking to retain their standard exhaust but want to have manual control over the exhaust valves opening, the German made Cargraphic exhaust valve controller is the product to do just that. It is installed between the exhaust valves and the factory control unit and gives the driver control over the exhaust valves.
Available in either 2-mode or 3-mode variants, the units function as follows:
2 Mode Unit:
Sport Mode - Exhaust valves are permanently open, regardless of RPM.
Automatic Mode - Factory valve control is used
3 Mode Unit:
Comfort Mode - Exhaust valves are permanently closed, regardless of RPM.
Sport Mode - Exhaust valves are permanently open, regardless of RPM.
Automatic Mode - factory valve control is used
The different modes are selected from the wireless remote, and these kits come with 2 remotes. This is a plug-and-play kit so can be removed without leaving a trace.
Fits the following models:
- Porsche 911 (991.1) GT3 (3.8L) | GT3 RS (4.0L) | R (4.0L)
