Our take on the MagnaFlow Direct Fit Catalytic Converter 49070

The MagnaFlow 49070 is a direct-fit catalytic converter for the 2002–2004 Jeep Grand Cherokee with the 4.7L V8. It bolts on in place of the factory unit with no cutting or welding, using mandrel-bent stainless steel tubing and a single laser-fusion weld to match the original geometry and reduce leak risk. It is EPA federal-compliant and interchanges with several OE part numbers, but it is not legal for sale or installation in California, Colorado or New York. Shoppers compare it with OE replacements and universal-fit converters: it costs less than a dealer part and installs faster than a weld-in universal, though it is not a CARB-approved part for those three states.

About the MagnaFlow Direct Fit Catalytic Converter 49070

The MagnaFlow 49070 is a direct-fit catalytic converter for the 2002-2004 Jeep Grand Cherokee with the 4.7L engine. It is an OEM-grade replacement designed to meet or exceed Federal EPA emissions requirements. It complies with legal standards for OBDII Federally registered vehicles with California or Federal/EPA emission systems.

The converter is built from 16 gauge 409 stainless steel tubing for corrosion resistance. Mandrel-bent tubing keeps the original design and geometry for smooth exhaust flow. A single laser fusion weld replicates the OE design and reduces the chance of a leak. The compact, low-mass design allows for greater thermal efficiency.

Fit and function were developed using 3D scanning, so the part matches the original equipment. It installs with the proper tools, and no cutting or welding is required. Gaskets and hardware are included. It is not legal for sale or installation in California, Colorado or New York.
