This is a direct-fit catalytic converter designed specifically for the 2000-2004 Toyota Tundra. It is a CARB-compliant California Grade part, designed to meet or exceed California Air Resources Board requirements. It has undergone additional testing so it can be used legally in California and CARB-restricted states on the listed vehicles.
The converter has a spun body design that replicates the original equipment. A single laser fusion weld reduces the possibility of a leak. The compact, low-mass design allows for greater thermal efficiency. Mandrel-bent tubing keeps the original design and geometry for smooth exhaust flow, and the flow dynamics are meant to maintain factory performance and fuel efficiency.
It installs with the proper tools, with no cutting or welding required. Gaskets and essential hardware are included. Fit was developed using 3D scanning so the part fits and functions like the original equipment.
