Subaru WRX Performance Exhaust - COBB Cat-Back (02-07 WRX, 04-07 STI). This titanium system replaces the exhaust from the catalytic converter back, delivering a crisp, performance-oriented tone and improved flow for your GD-chassis Subaru.

Built by COBB for enthusiasts, this cat-back offers a straightforward bolt-on fit that uses factory-style hangers. Lightweight titanium resists corrosion and helps reduce mass, while careful routing supports efficient exhaust evacuation. As a true cat-back, it retains factory catalytic converters and works well with stock or upgraded components, making it a solid choice for a reliable, refined sound and balanced performance.
