exhaust bypass valves. This is the stock operation.
- Always Open: Selecting this mode will force the exhaust bypass valves
to the open position — and remain open. When the valves are Always Open,

exhaust bypass valves to remain closed at all times. This overrides the
ECU control which opens the valves at predetermined engine and vehicle
speeds. This mode is especially useful to ensure that your vehicle is as

stay in the closed position at all times. This feature was added at the
request of people who track their cars at locations with strict noise
standards and did not want the vehicle ECU to open the valves at high
