AWE Tuning SwitchPathﾙ Technology.

AWE Tuning SwitchPathﾙ Technology responds to the exhaust valve commands sent from your BMW ECU, dependent on your throttle input and M Sport button setting. This means that the AWE Tuning F80 M3/F8x M4 SwitchPathﾙ Exhaust will transform from a sophisticated "Touring" note to an aggressive "Track" note with the touch of the M Sport button or throttle position.

In other words, exhaust volume is civil when you want it, and quite disobedient when you're in the mood.

The volume game: From civil to disobedient.

We've spent the majority of our R&D time perfecting the AWE Tuning F80 M3/F8x M4 Exhaust Suite to provide options for virtually every taste:

• Non-Resonated SwitchPathﾙ 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 M4, with a slightly higher part-throttle / highway cruising volume (non-returnable due to sound preference).
• Non-Resonated SwitchPathﾙ Exhaust with aftermarket downpipes: If you have to ask, this isn't your system (non-returnable due to sound preference).
