Magnaflow Direct-Fit Catalytic Converter 5461227 for 2004–2007 Pontiac Grand Prix is a California-grade, CARB-compliant replacement designed to keep emissions legal and prevent a check engine light. It installs using factory-style connections with no cutting or welding required when proper tools are used.
This converter replicates OE flow dynamics thanks to MagnaFlow's 3D-scanned development process and spun-body design. Constructed with high-strength 16 gauge 409 stainless steel tubing and mandrel-bent passages, it promotes smooth exhaust flow to maintain factory performance and fuel economy. A single laser fusion weld reduces leak points, and the compact, low-mass design improves thermal efficiency. The unit includes gaskets and hardware and uses OE-sized barbed exhaust hangers made from corrosion-resistant 410 stainless steel to help minimize noise and vibration. This part is CARB tested and listed for legal use in California and other CARB-regulated states for the listed vehicles.
