MagnaFlow Conv DF 04-06 Ford F-150 Pickup 5.4L 4WD (Exc Heritage Edition) P/S (49 State)

If you're working on a 2004-2008 Ford F-150 with the 5.4L engine, this direct-fit catalytic converter from Magnaflow is designed to get your exhaust system back to factory specifications. It's built to meet EPA emissions requirements, which helps ensure your check engine light stays off and your truck passes emissions tests in 49 states. This is a crucial part for maintaining your truck's performance and keeping it street legal.

Magnaflow uses 16-gauge 409 stainless steel tubing for this converter, giving it solid corrosion resistance for a long service life. The internal tubing is mandrel-bent to maintain smooth exhaust flow, just like the original part, which helps keep engine efficiency and fuel economy consistent. They also use 308 stainless steel for the MIG welds, which are applied with precision to reduce the chance of leaks. The collector design is also sized to match the OE specifications for optimal exhaust flow. Magnaflow uses 3D scanning technology during their design process to ensure this converter fits precisely and functions like the factory unit, making installation straightforward. You won't need to cut or weld anything; it bolts right up using the included Torca AccuSeal clamp and other necessary hardware, which is a big help when dealing with potentially corroded factory parts.

This converter is designed for 4WD models and excludes the Heritage Edition. It's important to note that this converter is not CARB approved and cannot be shipped to California. It directly replaces OE parts like 4L3Z-5E212-GE and L3Z5-E212-GB.
