The AWE SwitchPath valved exhaust for the Audi B9 S4 Sportback is a complete, non-resonated Track Edition package with non-resonated downpipes, an x-pipe and a Sportback-specific mid merge to produce an unapologetically loud soundtrack. Two valved muffler sections can be run by the SwitchPath remote or factory programming to switch between quiet and aggressive tones. Tip choices and adjustable, double-walled finishes are included; this rowdy edition is known to be loud and carries a no-return sound preference note.
