FAQs

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.

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 top / open button on the remote, opens the valves fully. Pressing the bottom / close button on the remote, reverts the exhaust motor back to normal car operation.

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.

How much is shipping?

SHIPPING IS FREE anywhere in the world. We also offer an express shipping upgrade which is much faster if you can't wait to turn your exhaust to 11. Please read our Shipping Policy for more information.

What countries do you ship to?

We ship anywhere in the world, exceptions may apply, please contact us if you have trouble placing your order. See our Shipping policy page for more information.
