Automatic Exhaust valve
Anybody ever seen this product ?
With this product you can program the valve in the exhaust to open or close or to monitor the right back pressure in the exhaust so it opens when pressure gets to high. You can also pre program it for different settings...... all with the remote controle. It is standaard set for valve opening in sport mode and closed mode for cruising... hence less sound. |
