AWE Tuning SwitchPath™ Exhaust Technology is a proprietary solution that utilizes valves in the exhaust to control tone and volume. Controlled by a combination of throttle input and engine speed, SwitchPath™ Technology keeps the S3 quiet and comfortable while cruising, but give it the boot and you’ll unlock an aggressive and exotic exhaust note.

Valve Simulators: Why do you need them?

Sound perfection comes standard thanks to AWE Tuning SwitchPath™ Technology, which utilizes the S3’s factory valving. But when it comes to the Track Edition versions of these systems, these valves are eliminated, the ECU stores what is known as a ‘soft code’ in the system. While this code is not harmful, who wants it? Enter the AWE Tuning Electronic Valve Simulators.

These simple devices plug right into the factory harness in place of the exhaust valves, and prevent any code from ever being stored in the ECU due to the removal of the exhaust valves. Plug them in. Start it up. Drive away. That simple. Comes as a set of two.

About the AWE Tuning SwitchPath™ Remote:

Push-button mood control.

• Open and close exhaust valves with the push of a button from inside the cabin at any time
• Works with stock system, or AWE Tuning SwitchPath™ Exhaust
• Comes as a set of two remotes with wiring harness, control box and mounting hardware
• Compact design perfect for a keychain or cup holder
• From quiet to aggressive with the tap of a button

What it does:

The AWE Tuning SwitchPath™ Remote and accompanying control box overrides the factory valving to allow the exhaust valves, whether it be on the AWE Tuning SwitchPath™ Exhaust or the stock exhaust, to be opened or closed manually via the SwitchPath™ Remote.

How to operate:

With the AWE Tuning SwitchPath™ Controller installed, the exhaust valves can be opened by pressing the “On” button found on the left side of the SwitchPath™ Remote. To close the exhaust valves simply press the “Off” button on the right side of the remote.

Please note, the AWE Tuning SwitchPath™ Remote overrides the stock valve control, meaning the exhaust must be opened and closed with the remote as desired.
