Valved Catback Exhaust for Audi S3 (8V) (2015–2020)

This valved catback exhaust system allows you to switch anytime between quiet OEM-style refinement and a louder, deeper, sportier performance tone. Built from high-grade 304 stainless steel with precision TIG welding, it offers excellent durability, corrosion resistance, and a clean premium finish. The system is fully bolt-on — no cutting or welding required — making installation straightforward for most professional exhaust shops. Designed specifically for the 2.0T EA888 engine in the Audi S3 8V, it improves exhaust flow and throttle response while delivering a sharper, fuller, and more dynamic exhaust note when the valve is open, yet maintaining refined comfort when closed.

Fitment: Compatible with Audi S3 (8V, 2015–2020) in sedan and sportback body styles equipped with the 2.0T engine and quattro drivetrain. Fitment can be confirmed using VIN or a rear exhaust photo.
