Valved Catback Exhaust for Audi S5 (B8) (2008–2012)(V8)

This valved catback exhaust system allows you to switch anytime between quiet OEM-style comfort and a louder, more aggressive performance tone. Built from high-grade 304 stainless steel with precision TIG welding for durability, corrosion resistance, and a clean premium finish. The system is fully bolt-on — no cutting or welding required — making installation simple for most exhaust shops. Engineered to improve exhaust flow and throttle response, it gives the B8 S5 a deeper and sportier exhaust note compared to the stock system, especially noticeable when the valve is open.

Fitment: Compatible with Audi S5 B8 Platform V8 (2008–2012). Fitment can be confirmed with a VIN or a rear exhaust photo if needed.
