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 AWE 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, or factory valve programming. Sneaking out in the morning? Keep the valve closed. Ready to rumble? Open the valve and let them know you're coming. All tip options include the AWE logo, and double walling to ensure a mirror finish even under hard usage. All tips are individually adjustable, allowing depth into the bumper to be set according to personal taste. Pro tip: we recommend and encourage pairing the SwitchPath™ Exhaust with the SwitchPath™ Remote versus using the factory operation for the best SwitchPath™ experience. Meet the perfected B9 S4 soundtrack.Note: you may notice a slight valve 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.
