Valved Catback Exhaust for Audi Q8 (4MN)(2019–2023)

This valved catback exhaust system allows you to switch anytime between quiet OEM-style comfort and a louder, deeper, more aggressive performance tone. Constructed from high-grade 304 stainless steel with precision TIG welding, it delivers excellent durability, corrosion resistance, and a clean factory-style finish. The system is fully bolt-on — no cutting or welding required — making installation straightforward for most exhaust shops. Engineered for the Q8’s turbocharged V6 engine, it improves exhaust flow and throttle response while producing a fuller, sportier, and more dynamic exhaust note when the valve is open, while maintaining OEM-level refinement when closed.

Fitment: Compatible with Audi Q8 (4MN)(2019–2023), including Premium / Premium Plus / Technik / S-line trims with the 3.0T V6 engine. Fitment can be confirmed using VIN or a rear exhaust photo.
