Magnaflow 2004 Ford F-150 5.4L Direct Fit Converter

If you're working on a 2004 Ford F-150 with the 5.4L engine and need to replace the catalytic converter, this Magnaflow Direct-Fit unit is a solid option. It's designed to keep that check engine light off and meet strict emissions standards, especially if you're in California or another CARB-restricted state. Magnaflow puts a lot of effort into making sure these converters fit just like the original equipment, using 3D scanning during their research and development.

What sets this converter apart is its construction. It's built with free-flowing, mandrel-bent tubing and uses highly corrosion-resistant 16-gauge 409 stainless steel for the tubing, which means it should hold up well against rust and last a long time. The spun body design replicates the OE style, and the single laser fusion weld is done carefully to greatly reduce the chance of leaks. This compact, low-mass design also helps with thermal efficiency, getting up to operating temperature quickly.

The best part about this converter is that it's a direct-fit. That means no cutting or welding is required for installation, making the job much simpler with the proper tools. Magnaflow includes the essential gaskets and hardware you'll need to get it installed right out of the box. This converter is specifically designed to meet or exceed California Air Resource Board requirements and has passed additional testing for legal use in California and other CARB-restricted states.
