11Mode Exhaust Controller – BMW G80/G81 M3

Take full control of your exhaust

Did you know race / track / sport modes don’t actually leave your exhaust valves open?

Regain control of your exhaust and open valves whenever you want.

Unlock the sound your car hides when the valves are closed.

How does it work?

At a press of a button {∿}, keep your car’s exhaust valves completely open.

Press the ON / open / 11MODE (∿) button and bypass your car’s control of the exhaust flaps and keep them fully open.

Press the OFF / close / quiet (—) button and return the valve control back over to the car, and the exhaust acts like normal.

The valves are never forced closed.
