MagnaFlow Conv DF 300/Magnum/C OEM

If your check engine light is on and you suspect a bad catalytic converter on your 2005-2010 Chrysler 300, this direct-fit unit from Magnaflow is a solid option. It's designed to replace the original equipment, helping you pass emissions tests and keep your car running smoothly. Magnaflow builds these converters to meet or exceed Federal EPA emissions requirements for OBDII vehicles registered in states with Federal/EPA emission systems.

This converter is constructed with high-strength 16-gauge 409 stainless steel tubing, which offers excellent resistance to corrosion and a long service life. The internal design uses free-flowing, mandrel-bent tubing to replicate the original equipment's flow dynamics, ensuring factory-level performance and fuel efficiency. Magnaflow uses advanced 3D scanning during their research and development to ensure a precise fit, and the single laser fusion weld is designed to significantly reduce the chance of leaks. The compact, low-mass design also contributes to greater thermal efficiency.

Installation is made easier because this is a direct-fit unit, meaning no cutting or welding is required, just proper tools. Magnaflow includes an O2 port plug and a nut to help with the installation. This converter is designed to interchange with several original equipment part numbers, including 4578 356AA and 4581 744AD.
