From the masters of S4 performance, AWE proudly presents the B9 S4 exhaust solution. Signature AWE tone, performance, and options for every taste and budget.
The SwitchPath™ valved solution is for those who want complete control of their S4’s volume and tone, at their fingertips.
The SwitchPath™ Exhaust comes complete with non-resonated downpipes, a precision-engineered x-pipe mid-section, and two valved muffler sections which can be controlled via the SwitchPath™ Remote.
Sneaking out in the morning? Keep the valve closed.
Ready to rumble? Open the valve and let them know you’re coming.
Pro tip: we recommend and encourage pairing the SwitchPath™ Exhaust with the SwitchPath™ Remote versus using the factory operation for the best SwitchPath™ experience.
Note: you may notice a slight rattle upon cold start as you would with many factory valved systems. This sound will go away within a few minutes and you will be off to the races in no time.
Sound Perfection: AWE 180 Technology®
Perfect tone, compliments of AWE 180 Technology®.
As exhaust gases exit the 3.0T engine and flow into an AWE 180 Technology® equipped resonator, they pass through strategically located ports, and into reflection chambers. Sound waves, carried by these exhaust gasses, bounce off the walls of the reflection chambers. By controlling the size and location of the ports and the chambers, we also control when the sound waves exit the chambers.
