Chevrolet Colorado Performance Exhaust - aFe - ROCK BASHER Cat Back - `23-`25 is a direct-fit cat-back system engineered for the 2023–2025 Colorado/Canyon L4 2.7L (t). It replaces the factory rear section with a rugged 3" 409 stainless system that delivers a deeper, more aggressive exhaust note while maintaining OE-style fitment.

Built from 3" mandrel-bent 409 stainless steel tubing and a high-flow 409 stainless muffler, this ROCK BASHER cat-back is designed for long-term durability and improved exhaust flow. The system uses a factory-style flange and hangers for a true bolt-on installation with no cutting or modifications required. A heavy-duty flex pipe with an internal interlock liner adds strength where it’s needed most, and the hi-tuck tip provides extra clearance for off-road angles and rough terrain. CAD-guided fitment and 100% MIG welding ensure consistent construction and reliable performance for enthusiasts wanting a stout, dependable upgrade.
