Valved Catback Exhaust for Audi S5 (B9) (2018–2024)

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 straightforward for most performance exhaust shops. Engineered to improve airflow and throttle response, it delivers a deeper, sharper, and more dynamic exhaust note compared to the factory system, especially noticeable when the valve is open.

Fitment: Compatible with Audi S5 B9 Platform (2018–2024) — including Coupe, Sportback, and Cabriolet models. Supports AWD quattro configurations. Fitment can be confirmed with a VIN or rear exhaust photo if needed.
