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.
