Catback exhaust systems replace the exhaust components from the catalytic converter back, improving exhaust flow, sound, and overall performance. These systems are a popular upgrade for Subaru WRX and STI owners looking to enhance exhaust tone while maintaining compatibility with factory or aftermarket downpipes.

Catback exhausts are designed to balance sound, performance, and daily drivability. Depending on design, they can deliver a more aggressive exhaust note while minimizing unwanted drone and maintaining comfort for street-driven vehicles.
