Valved Catback Exhaust for Audi A4 (B8)(2008–2016)

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 professional exhaust shops. Engineered to improve airflow and throttle response, it gives the B8 A4 a deeper and sportier exhaust note compared to the stock system, especially noticeable when the valve is open.

Fitment: Compatible with Audi A4 B8 Platform (2008–2016) — including sedan and Avant models, FWD and quattro. Fitment can be confirmed using VIN or a rear exhaust photo if needed.

What’s Included: Mid-pipe + rear valved catback system, mounting hardware and clamps, and a wireless valve controller or OEM-style valve integration depending on configuration.

Sound Characteristics:

• Cold Start: deeper and more noticeable tone

• Valve Open: loud, sporty, and performance-oriented exhaust note

• Valve Closed: close to OEM comfort — suitable for daily driving and late-night use
