How does it work?

The 11MODE Exhaust Controller bypasses your car's exhaust valve control and fully opens the valve whenever you want.

• Pressing the ON top ( ∿ ) button on the remote, opens the valves fully.
• Pressing the OFF bottom ( – ) button on the remote, reverts the exhaust motor back to normal car operation.

Note the controllers do not force the valves closed when OFF. So if the car has opened the valves already, pressing the controller OFF button will not close the valves.
