Valved Catback Exhaust for Mazda 3 (BP) (2021–2025)(2.5L)

This valved catback exhaust system allows you to switch anytime between quiet OEM-style comfort and a louder, deeper, more aggressive turbocharged tone. Constructed from high-grade 304 stainless steel with precision TIG welding, it offers strong durability, corrosion resistance, and a clean premium finish. The system is fully bolt-on — no cutting or welding required — making installation simple at most exhaust shops. Designed specifically for the 2.5L engine in the Mazda 3, it improves exhaust flow and throttle response while delivering a sharper, stronger, and more dynamic exhaust note when the valve is open, while maintaining OEM-like refinement when closed.

Fitment: Compatible with Mazda 3 (BP Platform, 2021–2025), including hatchback and sedan models equipped with the 2.5-liter engine. Fitment can be confirmed using VIN or a rear exhaust photo.
