AWE Tuning SwitchPath™ technology responds to the exhaust valve commands sent from your ECU, dependent on your throttle input and M-Sport button setting. This means that the AWE Tuning SwitchPath™ Exhaust will transform from a sophisticated “Touring” note to an aggressive “Track” note with the touch of the M-Sport button or throttle position.

AWE Tuning provides options for virtually every taste:

Resonated SwitchPath™ Exhaust with your stock downpipes: This is the most sophisticated of the lot, while still announcing that you’ve arrived. Aggressive when you want it, yet refined at part throttle and highway speeds. This exhaust brings out the natural tone of the motor without compromising neighborhood relations.

Resonated SwitchPath™ Exhaust with your aftermarket downpipes: Your volume is already turned up with your aftermarket downpipes, but chances are you may want a bit more sophistication and refinement without losing the aggressive yell of the twin turbo engine. This is the system that makes de-catted downpipes a bit more suitable for daily usage.

Non-Resonated SwitchPath™ Exhaust with your stock downpipes: This is an aggressive set up, with sharper edges. It announces your entry while still maintaining trademark AWE Tuning sophistication. We recommend this combination for those looking for more full throttle growl from their car, with a slightly higher part-throttle / highway cruising volume.

Non-Resonated SwitchPath™ Exhaust with your aftermarket downpipes: If you have to ask, this isn’t your system.

Exhaust incorporates a proprietary mechanical valve system that controls sound volume: Under part throttle and idle, valves route exhaust gasses through a central muffler, keeping sound tame and drone free. At 3/4 throttle application and more, the valves open and the system is unleashed – going into "straight pipe" mode. An in-cabin mounted electronic SwitchPath™ Remote toggles the mechanical valves between "normal" and "straight pipe mode.
