MagnaFlow California Grade Direct-Fit Catalytic Converter 4551038 for 2004-2005 Buick Rendezvous — a direct OE-replacement designed to maintain emissions compliance while restoring proper exhaust flow. This California direct-fit converter installs without cutting or welding when using the proper tools.
Built with highly corrosion-resistant stainless steel and mandrel-bent tubing, this MagnaFlow unit replicates OE spun-body geometry to help preserve factory flow dynamics and engine operation. The spun-body design with a single laser fusion weld reduces potential leak points and the compact, low-mass construction supports thermal efficiency. Included gaskets and hardware simplify installation and avoid reusing corroded factory parts. This converter is engineered to meet California Air Resources Board requirements and has undergone the additional testing required for legal use in California and other CARB-regulated states for the listed vehicles.
