Our take on the MagnaFlow Direct Fit Catalytic Converter 00-04 Tundra Rear 3.4L

This is a CARB-compliant direct-fit rear catalytic converter for the 2000–2004 Toyota Tundra with the 3.4L V6. It bolts on in place of the factory unit with no cutting or welding, and it interchanges with OE parts 17403-07021 and 17403-07022. The spun body, single laser-fusion weld and stainless construction are built to resist leaks and corrosion, and the mandrel-bent tubing keeps exhaust flow close to stock. It suits Tundra owners in California and CARB-restricted states who need a legal replacement, and it costs more than generic universal converters because of the CARB certification and vehicle-specific fit.

About the MagnaFlow Direct Fit Catalytic Converter 00-04 Tundra Rear 3.4L

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.
