XForce AUDI RS3 8V Sedan Varex Valved Cat Back Exhaust System with SmartBox

Elevate the sound experience of your Audi 8V RS3 with our newly refined and improved XFORCE cat-back exhaust system. Designed to fit seamlessly to the factory slip joints, this system offers an effortless upgrade for both pre-facelift and post-facelift models.

At the core of this system is a single 3.5” mandrel-bent pipe, allowing for optimal flow and a deep, aggressive exhaust note. This leads into our latest VAREX valved rear muffler, giving you full control over your RS3’s sound—switch between an exhilarating, race-inspired roar and a refined, street-friendly tone at the push of a button.

The system then reduces into dual 2.5” outlets, finished with polished oval tips, perfectly complementing the factory rear bumper for an OEM+ aesthetic with a true performance edge.

Take sound control even further with the XFORCE SmartBox—the most advanced exhaust control system on the market. With four unique modes, you can tailor your exhaust to match any driving situation:

• Matrix Mode – Fully customizable valve control based on RPM, throttle input, and speed.
• Manual Mode – Open or close the valves at any time via the SmartBox app or key fob.
• Geo Mode – Set your exhaust to automatically adjust based on your location.
• Factory Drive Mode Integration – Sync your exhaust settings with Audi’s built-in drive modes for a seamless experience.

Experience the sound your RS3 deserves—deep, throaty, and commanding when open, yet sophisticated and refined when closed. Whether you're carving through backroads or cruising the city, this system puts unparalleled sound control at your fingertips.
