Magnaflow 2004 Jeep Grand Cherokee 4.7L Direct Fit Converter

For the 2004 Jeep Grand Cherokee 4.7L, MagnaFlow offers this CARB compliant direct-fit catalytic converter as a bolt-on replacement for the factory unit. It interchanges with OE parts 5208 0358AA, 5208 0378AB, and 5208 0378AC, so you can confirm the match before ordering.

MagnaFlow uses mandrel-bent 16-gauge 409 stainless steel tubing to keep the exhaust flowing smoothly through the converter. The design was developed using 3D scanning to replicate the factory geometry, which means the overall shape and hanger positions line up with the original. The OE-sized barbed exhaust hangers are made from 410 stainless steel for corrosion resistance, and they help reduce noise and vibration transmitted through the exhaust system. At the welds, 308 stainless steel MIG joints tie the assembly together, and the precision-stamped collector design supports consistent exhaust flow.

Installation requires no cutting or welding. The included gaskets and hardware let you make a clean connection without reusing your old corroded parts. This converter meets California Air Resources Board emissions standards, making it legal for sale and installation in all 50 states. Just confirm your vehicle's Executive Order number and Engine Family Number appear in this converter's CARB Executive Order before proceeding with the install.
