May suit other models and years, message us if you're unsure.

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.
Loud when you want. Quiet when you need. At the press of a button.

How does it work?

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

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

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.

Turn your exhaust to 11 in minutes

What's Included?

- Exhaust Controller to suit your car.

- For two-valved cars, two Exhaust Controllers: one for the left side, one for the right side. These are interchangeable.

• For one-valved cars, one Exhaust Controller is all you need.

- One remote to control your exhaust.

- That is all you need to turn your exhaust to 11.

Why do I need this?

Your car does not fully open the exhaust valves. Although your car does have a "loud mode" either race, track or some other variation, that opens the exhaust valves, in reality it does not actually fully open the valve and even closes at certain engine or car speeds. The 11MODE Exhaust Controller gives you full control to open your exhaust up to 11.

I have an aftermarket exhaust, will it work?

If your aftermarket exhaust retains your factory exhaust valve actuators / motors, then the Exhaust Controller will still work.

If your car normally has only one valve motor but the aftermarket exhaust now has two valve motors, please let us know or leave a comment in the order notes.

Why does the ( — ) button not close the valves?

Forcing the valve closed could potentially cause damage to the engine and exhaust system, because if the ECU requires the valve to be open, but it is forced closed, it may be detrimental to the car's safety or performance. That is why pressing the close button reverts the exhaust motor control back to normal car operation, instead of forcing the valve closed and potentially causing damage.

Does it have a memory function?

The controllers return back to normal car control for the default state by design. This allows the car to calibrate the valves upon startup if need be. So you will need to press the open button upon each startup or with the ignition to open the valves.
