The MagnaFlow 51944 is a direct-fit catalytic converter for 2000-2004 Toyota Tacoma trucks with the 3.4L V6. It bolts on in place of the factory unit with no cutting or welding, and MagnaFlow 3D-scans the original part so the fit and flange angles match OE. It is built from stainless steel with mandrel-bent tubing and a single laser-fusion weld to limit leaks. It is EPA federal compliant, not California CARB legal, so check your state's rules before buying. Against universal-fit converters it costs more but saves fabrication time and avoids fitment guesswork.

Owners of older Tacomas generally report the 51944 bolts up to the factory flanges and clears the check engine light. Complaints center on price versus universal converters and on fitment confusion between engine sizes.
The MagnaFlow 51944 is an OEM Grade, Direct-Fit catalytic converter for 2000-2004 Toyota Tacoma models with the 3.4L engine. It is 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. It copies the OE design, and a single laser fusion weld reduces the chance of a leak. The compact, low-mass design allows greater thermal efficiency. MagnaFlow used 3D scanning systems during development so the part fits and functions like the original equipment.
It installs with the proper tools. No cutting or welding is required. Two flat ring gaskets are included.
