Magnaflow 2004 Ford F-150 5.4L Direct Fit Converter

You're looking at the Magnaflow California Grade CARB Compliant Direct-Fit Catalytic Converter, specifically made for your 2004 Ford F-150 with the 5.4L engine. This isn't just any converter; it's designed to keep that check engine light off and ensure your truck runs cleanly, especially if you're in California or another state with strict emissions rules. Magnaflow uses advanced 3D scanning to make sure this part fits exactly like the original equipment, so you won't have to worry about fitment issues.

What you get in the box are the essential gaskets and hardware needed for installation, making the job much simpler. The tubing is mandrel-bent, which means it maintains a consistent diameter throughout, eliminating restrictions and helping your engine breathe easier. It's built from high-strength 16-gauge 409 stainless steel for the tubing and uses durable 308 stainless steel MIG welds, so it's well-built to resist corrosion and last a long time. This design also helps with thermal efficiency, and the single laser fusion weld is done carefully to minimize the chance of leaks.

Because this is a direct-fit converter, you won't need to cut or weld anything to install it, assuming you have the right tools. It's designed to meet or even exceed California Air Resource Board (CARB) requirements, which is a big deal for legal operation in California and other CARB-restricted areas. This converter interchanges with OE parts 4L3Z-5E212-GC and 4L3Z-5E212-GD.
