Enhance Your Audi 8V RS3 with the XFORCE Cat-Back Exhaust System

Experience an elevated auditory journey with your Audi 8V RS3, courtesy of our refined and improved XFORCE cat-back exhaust system. This system is designed to integrate effortlessly with the factory slip joints, making it a straightforward upgrade for both pre-facelift and post-facelift models.

At the heart of this system lies a single 3.5” mandrel-bent pipe, designed for optimal flow and a deep, aggressive exhaust note. This leads into our latest VAREX valved rear muffler, offering you complete control over your RS3’s sound. With the simple push of a button, you can switch between a thrilling, race-inspired roar and a sophisticated, street-friendly tone.

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

Take sound control to the next level with the XFORCE SmartBox—the most advanced exhaust control system available. With four unique modes, you can adapt your exhaust to match any driving situation:

• Matrix Mode – Fully customisable 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.
