MagnaFlow Conv DF 98 Ford Expedition 5.4L

The 1997-1998 Ford Expedition 5.4L is a solid truck, and keeping its emissions system in check is key to its longevity and performance. This direct-fit catalytic converter from Magnaflow, part number 23718, is built to replace your original unit, helping to ensure your check engine light stays off and your vehicle runs cleanly. It's designed to meet Federal EPA emissions requirements, making it a legal and reliable replacement for OBDII Federally registered vehicles.

What sets this converter apart is its construction and design. It features free-flowing, mandrel-bent tubing, which means the inside diameter stays consistent throughout, allowing exhaust gases to exit more freely than with crushed bends. This helps maintain factory performance and fuel efficiency. The tubing itself is made from high-strength 16-gauge 409 stainless steel, chosen for its excellent resistance to corrosion and long service life, especially important for exhaust components. The compact, low-mass design also contributes to greater thermal efficiency, helping the converter reach its optimal operating temperature faster. Magnaflow uses advanced 3D scanning during their research and development to ensure this part fits and functions just like the original equipment, and the single laser fusion weld is designed to greatly reduce the possibility of leaks.

Installation is made simpler because this is a direct-fit unit, meaning no cutting or welding is required, and it includes essential gaskets and hardware. This converter interchanges with several OE part numbers, including F75Z-5E212-BF and F85Z-5E212-DB, and is designed for easy installation with the proper tools. Please note that this converter is not CARB approved and cannot be shipped to California.
