The volume game- From civil to disobedient. Choose your perfect setup:
AWE Tuning has invested countless hours and resources into research and development of the F8X M3/ M4 exhaust suite, to provide a bespoke option for every preference when it comes to the optimum exhaust set up. Whether you are looking for a more sophisticated and subdues setup, or an all out aggressive track exhaust, there is truly a setup fit for everyone's preference:
Resonated SwitchPath™ Exhaust with your stock downpipes: This is the most sophisticated of the setups, while still announcing that you’ve arrived. Aggressive when you want it, yet very refined at part throttle and highway speeds. This exhaust setup brings out the natural tone of the M4 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 M4, with a slightly higher part-throttle / highway cruising volume (non-returnable due to sound preference).
Non-Resonated SwitchPath™ Exhaust with aftermarket downpipes: If you have to ask, this isn’t your system (non-returnable due to sound preference).
AWE Tuning SwitchPath™ Technology.
AWE Tuning SwitchPath™ 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 F8x M4 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.
In other words, exhaust volume is civil when you want it, and quite disobedient when you’re in the mood.
