Magnaflow California Direct Fit Converter 05-07 Dodge Ram 2500 5.7L

For 2005-2007 Dodge Ram 2500 and 2004-2007 Ram 3500 owners with the 5.7L Hemi, this MagnaFlow direct-fit catalytic converter (part 5451358) goes in without cutting or welding. It matches the factory mounting points and exhaust routing, making the swap a bolt-on job.

MagnaFlow builds this converter with 16-gauge 409 stainless steel tubing that resists corrosion well in the harsh environment under a heavy-duty truck. The spun body design uses a single laser fusion weld to replicate the OE construction closely, which helps reduce the chance of leaks forming over time. Their engineering team uses 3D scanning during development to confirm the dimensions and fit align with factory specs, so you can expect the converter to line up correctly on the first attempt.

This is a CARB-compliant unit, legal for use in all 50 states including California, Colorado, New York, and Maine. Two Torca AccuSeal clamps come in the box, each distributing clamping force evenly around the full circumference to prevent pipe distortion. Hardware and gaskets are also included, eliminating the hassle of dealing with corroded factory fasteners.

The precision-stamped collector and 308 stainless MIG welds speak to the build quality throughout. If you need your Ram 2500 or 3500 to pass emissions or want to clear a persistent check engine light, this MagnaFlow converter covers the job with verified fitment and CARB certification behind it.
