• This is the second generation of electric Exhaust Cutout System. It is designed and used to enhance the performance, sound, and power of vehicles with the flip of the toggle switch.Designed to be conveniently welded onto anywhere from the cutout location from the header to the exhaust pipe of vehicles.
• Compared to the old Electric Exhaust Cutout, the new Electric Exhaust Cut Out Kit with vacuum pump has earned more positive feedback than ever before. Great changes Reflected in the following respects.
• The Vacuum valve installed At the bottom of the car is waterproof and can be used normally in a bad environment.
• The principle of vacuum valve makes sure it is more durable as the electric motor will be damaged by friction, while the vacuum valve controls the switch of valve slice by air pressure.
• We designed an air pump box and add signal lines which strengthen the contact between the remote and control box
• A separate vacuum pump controller is easy to connect. Don't need to connect to the car's vacuum pump to avoid damage for the car air pump.

1. When you use this kit, the vacuum pump valve will work every 140 seconds to check whether there is air leakage or not. So if you found the valve is closed by itself, you need to check the rubber hose and Vacuum valve if it leaks.
2. Remember the high temperature will destroy rubber hose so keep it away from the exhaust pipe when installing it.
