Valved Catback Exhaust for Mazda 3 Hatchback (BM/BN) (2014–2018)

This valved catback exhaust system allows you to switch anytime between quiet OEM-style comfort and a louder, deeper, more aggressive sport compact tone. Built from high-grade 304 stainless steel with precision TIG welding, it offers excellent durability, corrosion resistance, and a clean factory-style finish. The system is fully bolt-on — no cutting or welding required — making installation simple for most exhaust shops. Designed specifically for the 2.0L and 2.5L SkyActiv engines in the BM/BN Mazda 3, it improves exhaust flow and throttle response while producing a fuller, sharper, and more dynamic exhaust note when the valve is open, while maintaining smooth daily-driving comfort when closed.

Fitment: Compatible with Mazda 3 Hatchback BM/BN (2014–2018), including 2.0L and 2.5L SkyActiv models. Fitment can be confirmed using VIN or a rear exhaust photo.
