Valved Catback Exhaust for Ford Mustang V6 (S550) (2015–2017)

This valved catback exhaust system allows you to switch anytime between quiet OEM-style comfort and a louder, deeper, sportier naturally aspirated V6 tone. Built from high-grade 304 stainless steel with precision TIG welding, it offers excellent durability, corrosion resistance, and a clean premium finish. The system is fully bolt-on — no cutting or welding required — making installation straightforward for most professional exhaust shops. Designed specifically for the 3.7L Cyclone V6 engine in the S550 Mustang, it improves exhaust flow and throttle response while delivering a fuller, sharper, and more dynamic exhaust note when the valve is open, yet maintaining smooth daily-driving comfort when closed.

Fitment: Compatible with Ford Mustang V6 (S550, 2015–2017) coupe and convertible models equipped with the 3.7L naturally aspirated V6 engine. Fitment can be confirmed using VIN or a rear exhaust photo.
