Unlock the Full Performance Potential of Your Audi 8Y or 8V S3 Sedan with the XFORCE VAREX SmartBox-Equipped Cat-Back Exhaust System
Experience a new level of sound and control with the XFORCE VAREX SmartBox-equipped cat-back exhaust system, designed specifically to enhance your Audi 8Y or 8V S3 Sedan. This isn't merely an exhaust upgrade; it's a complete transformation of your driving experience.
Made from brushed 304 stainless steel, this system incorporates 3” mandrel-bent piping, a hot dog resonator, and a re-engineered VAREX valved rear muffler. The result is a bold, assertive tone when open and a sophisticated, near-stock sound when closed. It's perfect for everyday driving, but with the flexibility to make a statement when you want to.
When combined with our VAREX SmartBox, you gain the most advanced exhaust control available. Choose from:
Matrix Mode: Automatically adjust valve position based on speed, RPM, or throttle input.
Manual Mode: Fine-tune valve position in real time via the XFORCE app or remote.
Geo Mode: Programme valve behaviour by location—quiet in your neighbourhood, loud on your favourite backroad.
Factory Mode (with optional cable): Seamlessly link exhaust behaviour to your Audi’s built-in drive mode settings.
