Upgrade your Audi 8V RS3 Sedan with the XForce Varex valved cat-back exhaust system with SmartBox for enhanced exhaust flow and adjustable sound control. This system connects to the factory slip joints and features a single 3.5 in. mandrel-bent pipe feeding a Varex valved rear muffler, letting you switch between a quieter mode and a more aggressive exhaust note on demand. It then transitions to dual 2.5 in. outlets with oval polished tips for an OEM+ appearance. The included SmartBox control unit expands valve control through multiple modes and supports OEM drive mode connection for integrated operation. Built from 304 stainless steel, this kit is made to fit Sedan models only.
