This is a direct-fit rear catalytic converter from MagnaFlow 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 mandrel-bent stainless tubing mirror the original design to keep exhaust flow and fit close to stock. It is EPA federal-compliant, not California CARB-approved, so buyers in CARB states should look elsewhere. Against generic universal converters, the direct fit and OE-style body are the main advantages; the trade-off is a higher cost than weld-in universal units.

Owner feedback on MagnaFlow direct-fit converters is generally positive on fit and finish, with most reporting a straightforward bolt-on install and no check engine light afterward. Complaints tend to center on the premium over universal units and occasional fitment issues on modified or rusted exhausts.
This is a direct-fit replacement catalytic converter for the 2000-2004 Toyota Tundra. It is an OEM-grade, spun body design that replicates the original equipment, with a single laser fusion weld that reduces the possibility of a leak. The compact, low-mass design allows for greater thermal efficiency.
The tubing is mandrel-bent 16 gauge 409 stainless steel, which keeps the original design and geometry for smooth exhaust flow. The barbed exhaust hangers are OE-sized and made from 410 stainless steel to reduce noise and vibration. The welds are 308 stainless steel MIG welds.
It installs with the proper tools, with no cutting or welding required. Gaskets and hardware are included. The converter is designed to meet or exceed Federal EPA emissions requirements for OBDII Federally registered vehicles with California or Federal/EPA emission systems.
