AWE’s SwitchPath exhaust for the Audi B9 S4 pairs non-resonated downpipes with a precision x-pipe and valved mufflers to give drivers fingertip control over cabin volume and tone using the SwitchPath remote or factory valve logic. The system balances civility when closed with an aggressive howl when opened. Chrome silver 102mm tips are double-walled and adjustable for depth; the package includes the mid merge optimized for Sportback undercarriage.
