Our take on the MagnaFlow 2001-2004 Toyota Sequoia 4.7L OEM Grade Federal / EPA Compliant Direct-Fit Catalytic Converter 49578

The MagnaFlow 49578 is a direct-fit catalytic converter for the 2001-2004 Toyota Sequoia with the 4.7L V8. It bolts on with the included gaskets and needs no cutting or welding, and it interchanges with OE part 17410-0F020. It is built from stainless steel with mandrel-bent tubing and a single laser-fusion weld to reduce leak risk. It is EPA Federal compliant, so it is not legal for California-registered vehicles. Owners pick it over universal converters for the bolt-on fit and over the dealer part for the lower cost of a comparable stainless unit.

About the MagnaFlow 2001-2004 Toyota Sequoia 4.7L OEM Grade Federal / EPA Compliant Direct-Fit Catalytic Converter 49578

This is a direct-fit catalytic converter for the 2001-2004 Toyota Sequoia with the 4.7L engine. It is OEM grade and designed to meet or exceed Federal emissions requirements set by the EPA. It complies with legal standards for OBDII Federally registered vehicles with California or Federal/EPA emission systems.

The converter is built from highly corrosion-resistant stainless steel with free-flowing mandrel-bent tubing. Its compact, low-mass design allows for greater thermal efficiency. A single laser fusion weld, replicating the OE design, greatly reduces the possibility of a leak. The design was developed using 3D scanning so that it fits and functions like the original equipment.

It installs with the proper tools, with no cutting or welding required. It interchanges with OE part 17410-0F020.
