Subaru STi Performance Exhaust - COBB - Cat Back - `02-`07 is a direct-fit system for 2002–2007 WRX/STI. It brings a boxer rumble and improved flow while keeping factory catalytic components.

Crafted from stainless steel with mandrel-bent tubing, this cat-back reduces backpressure and supports responsive spool without harsh drone. A straight-through muffler and flanged connections help deliver consistent performance. The bolt-on layout uses factory-style hangers for a reliable fit on street or track builds, and pairs well with stock or tuned configurations.
