11MODE Questions, answered

Frequently asked questions

Your car doesn't fully hold your exhaust valves open, and in some models and modes they only open partially. Sport and race modes don't keep them open across every RPM, gear and speed. 11MODE gives you full control to open your exhaust up to 11 whenever you want.

11MODE bypasses your car's exhaust valve control and holds the valves fully open on demand. Press the top (open) button and the valves stay open. Press the bottom button and control reverts to normal car operation. It changes sound only and is fully reversible.

Yes. The controller remembers its last setting, ON or OFF, and automatically restores it the next time you start the car. This applies to orders placed after June 2026.

Off hands control back to your car rather than forcing the valves shut. Forcing them closed can risk engine damage if the car needs them open under load, so the button reverts to normal operation instead. Your car then runs the valves exactly as it normally would.
