Valved Catback Exhaust for Subaru WRX STI Hatchback (GR/GV) (2008–2014)

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 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 exhaust or performance shops. Designed specifically for the 2.5-liter turbocharged EJ25 engine in the 2008–2014 WRX STI Hatchback, it improves exhaust flow and throttle response while delivering a sharper, fuller, and more dynamic exhaust note when the valve is open, while maintaining OEM-like refinement when closed.

Fitment: Compatible with Subaru WRX STI Hatchback (GR/GV Platform, 2008–2014) — including performance trims equipped with the 2.5L turbo EJ25. Fitment can be confirmed using VIN or a rear exhaust photo.
