Valved Catback Exhaust for Audi A4 (B7) (2005–2008)

This valved catback exhaust system allows you to switch anytime between quiet OEM-style comfort and a louder, deeper, more aggressive tone. Built from high-grade 304 stainless steel with precision TIG welding, it provides excellent durability, corrosion resistance, and a clean factory-style finish. The system is fully bolt-on with no cutting or welding required, making installation simple for most exhaust shops. Designed for the B7 A4’s 2.0T, 1.8T and 3.2 V6 engines, it improves exhaust flow and throttle response while adding a fuller, richer, and more dynamic exhaust note when the valve is open, while maintaining refined comfort when closed.

Fitment: Compatible with Audi A4 B7 (2005–2008), including 1.8T 2.0T FSI and 3.2 V6 models in sedan, avant, and convertible body styles. Fitment can be confirmed with VIN or rear exhaust photo.
