The COBB Stainless Steel 3″ Cat-Back Exhaust for the 20222023 Subaru WRX delivers a perfect blend of aggressive sound, refined tone, and high-performance flow. Made entirely from 304 stainless steel and TIG welded for strength and durability, this system features a precision-engineered cast flange for a leak-free fit, a compliant flex joint, and a durable cast Y-split transitioning to dual bespoke COBB mufflers. Each muffler feeds into dual 3.5″ slash-cut, dual-wall tips that complete the look with laser-etched COBB logos. Whether you’re daily driving or hitting the track, this exhaust system provides a noticeable sound improvement without the cabin drone.
