GMC Sierra 1500 Catalytic Converter - MagnaFlow - California Grade CARB Compliant Direct-Fit - `07-`09. This direct-fit replacement converter is built to maintain proper emissions operation and help keep the check engine light off on 2007–2009 GMC Sierra 1500 models while meeting CARB-regulated requirements.
MagnaFlow's California Grade unit reproduces OE fit and flow characteristics using advanced 3D scanning during development. The spun body design with a single laser fusion weld reduces potential leak points, while a compact, low-mass assembly supports thermal efficiency. Constructed with mandrel-bent tubing and corrosion-resistant stainless steel, this converter installs without cutting or welding and includes gaskets and hardware to avoid reusing corroded factory parts. It is designed and tested to meet California Air Resources Board guidelines for the listed vehicles; installation is permitted only when the converter’s CARB Executive Order (EO) and Engine Family Number (EFN) match the vehicle.
