About this part

Product Details

Magnaflow is known for making exhaust components that flow well and last a long time. This direct-fit catalytic converter is built to keep your 2004 Dodge Durango running right and the check engine light off. It's designed to meet federal emissions requirements, so you can be confident it's compliant for OBDII registered vehicles with Federal/EPA emission systems.

This converter uses free-flowing, mandrel-bent tubing and is constructed from highly corrosion-resistant stainless steel, specifically 16-gauge 409 stainless steel for the tubing and 308 stainless steel for the welds. Magnaflow uses advanced 3D scanning during their research and development to ensure this part fits and functions just like the original equipment. The design replicates the OE spun body, and a single laser fusion weld is used to significantly reduce the chance of leaks. Its compact, low-mass design also helps with thermal efficiency.

Installation is made simpler because this is a direct-fit unit, meaning no cutting or welding is required – just use the proper tools. Essential gaskets and hardware are included in the box to help with the installation. This converter interchanges with OE parts 5285 5404AA and 5210 3679AB.
