GMC Canyon Catalytic Converter - Magnaflow - Direct Fit - `04-`06. This California-grade, CARB-compliant direct-fit catalytic converter is built to replace the factory unit on 2004–2006 GMC Canyons, providing OE-like flow characteristics and legal emissions performance for CARB-regulated states.
MagnaFlow designed this converter using 3D scanning and metrology verification to match factory fit and function. The unit uses mandrel-bent tubing and high-strength 16 gauge 409 stainless steel to resist corrosion and help maintain exhaust flow. Durable 308 stainless MIG welds and included gaskets/hardware simplify installation — no cutting or welding is required when installed with the proper tools. This part interchanges with OE numbers 19418950 and 12604221 and is also listed for compatible 2004–2006 Chevrolet Colorado applications. It meets CARB requirements and may be used where the converter’s CARB Executive Order (EO) and Engine Family Number (EFN) match your vehicle’s EO/EFN.
