Subaru WRX STI Performance Exhaust - COBB - Cat Back - `04-`07. A titanium cat-back built for the 2004–2007 WRX STI, offering a refined tone and efficient flow for spirited driving.
COBB’s cat-back replaces the factory system from the mid-pipe rearward with lightweight, corrosion-resistant titanium. Tuned for the EJ-powered WRX STI, it delivers a deep, assertive note while maintaining comfort for daily use. Precision fitment for 2004–2007 models and factory-style hanger locations make installation straightforward for DIY enthusiasts or pro shops, and its freer-flowing design reduces restriction versus stock.
