MagnaFlow 4651649 is the California Grade replacement for the passenger side converter pipe on the GM 6.0L trucks and SUVs, a spun body direct-fit assembly in 16 gauge 409 stainless steel with a ceramic substrate, mandrel-bent tubing and OE sized barbed hangers in 410 stainless. Overall length is 37.5 inches and the assembly carries two oxygen sensor ports, one ahead of the catalyst and one behind it, so the upstream and downstream sensors both return to factory locations. CARB Executive Order D-193-189 covers it for registered use in California and the other CARB states. An inlet gasket is supplied, and the flanged inlet and outlet mean no cutting or welding.
