AWE Tuning Audi B9 S4 SwitchPath? Exhaust - Non-Resonated (Diamond Black 90mm Tips)

SwitchPath™ Exhaust

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.
