Description
Give your Audi 8V S3 Hatch the soundtrack it deserves with the XFORCE Varex Valved Cat Back Exhaust System with SmartBox. Engineered for performance, sound control, and premium styling, this 3-inch high-flow exhaust system reduces backpressure while delivering an aggressive, race-inspired tone when you want it — and refined civility when you don’t.
Constructed from brushed 304-grade stainless steel, the 3” mandrel-bent pipework improves exhaust flow and durability. A center hot dog resonator helps balance tone, while the polished Varex R Series rear muffler integrates XFORCE’s signature VAREX valve technology. This system allows you to actively control exhaust volume through the included SmartBox controller, giving you full command of your S3’s sound profile from mild to wild.
The SmartBox system connects to an intuitive mobile app, unlocking exclusive functionality and real-time exhaust control. Whether cruising quietly through town or unleashing full performance on demand, the VAREX system adapts instantly to your driving style.
Finishing touches include precision TIG welds, a clean brushed stainless appearance, and quad 4-inch polished stainless steel tips that perfectly complement the aggressive styling of the 8V S3 Hatch.
This system is a direct-fit cat back solution designed specifically for the Audi 8V S3 Hatch, delivering performance gains, sound customization, and premium construction in one complete package.
