What makes this catalytic converter a direct-fit?

This converter is designed using 3D scanning to precisely match the original equipment's fit and geometry. It uses OE-sized barbed hangers and requires no cutting or welding for installation, simplifying the process.

What materials is this catalytic converter made from?

The tubing is made from high-strength 16-gauge 409 stainless steel for exceptional corrosion resistance and a long service life. The welds are durable 308 stainless steel.

Product Details

Magnaflow is well-known for making exhaust components that flow well and sound great. This direct-fit catalytic converter, part number 24441, is built specifically for your 2003-2004 Ford Expedition with the 4.6L engine, and it's designed to keep your check engine light off by meeting Federal emissions standards.

This converter uses mandrel-bent tubing, which means the bends are consistent and don't restrict exhaust flow, helping maintain your truck's original performance and fuel economy. It's constructed from strong 16-gauge 409 stainless steel tubing for excellent corrosion resistance, so it should last a long time. Magnaflow uses 3D scanning during their design process to make sure this converter fits just like the factory original, and the single laser fusion weld helps prevent leaks. It's designed to be a direct replacement, meaning no cutting or welding is needed for installation, making it a straightforward job with the right tools.

This converter is designed to meet or exceed EPA requirements for OBDII federally registered vehicles. It interchanges with several OE part numbers, including 2L1Z-5E212-AB and 4L1Z-5E212-AB. Keep in mind that this converter is not CARB approved and cannot be shipped to California.
