Dodge Durango Catalytic Converter - MagnaFlow - Direct-Fit - 2004. This OEM-grade MagnaFlow converter (part 51770) is a direct-fit replacement designed specifically for the 2004 Dodge Durango to restore proper emissions control and reliable operation.
Built with MagnaFlow’s documented R&D and precision manufacturing, this direct-fit converter replicates OE spun-body geometry and uses mandrel-bent tubing to preserve exhaust flow and engine performance. The compact, low-mass design promotes thermal efficiency while a single laser fusion weld reduces potential leak points. It installs without cutting or welding using the supplied gaskets and hardware, making it a practical option for experienced DIY installers or professional shops. Designed to meet Federal (EPA) emissions requirements for OBDII vehicles; not legal for sale or installation in California, Colorado, or New York.
