FEATURES

The Sturmbock Germany valve-tronic set up allows you the opening and closing of exhaust valves manually, via an exclusive switch made out of stainless steel with red LED illumination when on, making the exhaust sporty and deeply loud when you want it or classic quiet when you need it (e.g. when you leaving early in the morning).

This feature makes it a very unique and personalised exhaust system with a sophisticated and elegant valve opening solution. It gives you the great option to select the exhaust sound level depending what noise level you like or prefer.

The operation is done via a button with red LED illumination.
The button can be custom-installed in the centre console area, an empty console switch or wherever you feel is the best accessible place for it.

If button is on ON position, valves are open, creating the top deep sound all the time.
If button is on OFF, valves only open at a per-programmed RPM, for example at 4500 rpm. So up to 4500 rpm the exhaust operates in quiet mode and then above it will open up automatically and be loud again.
You can choose at what RPM the valves should open, if you wish, otherwise our technicians will set the exhaust opening rpm at the recommended level.

It is a very elegant solution and the sound is amazing.
