MagnaFlow Conv DF 03-04 Exped 4.6L Driver Side

If your 2003 or 2004 Ford Expedition with the 4.6L engine is showing a check engine light related to emissions, it's likely time to replace the catalytic converter. This direct-fit unit from Magnaflow is designed to get your truck running cleanly again, meeting Federal and EPA emissions standards for OBDII vehicles. It's built to function just like the original equipment, ensuring your truck passes emissions tests and runs smoothly.

Magnaflow builds this converter with 16-gauge 409 stainless steel tubing, which is known for resisting corrosion and lasting a long time. The tubing is mandrel-bent to maintain consistent diameter and smooth airflow, preventing restrictions that can hurt performance and fuel economy. They use 308 stainless steel for the MIG welds, which are laser fusion welded to closely replicate the original design, greatly reducing the chance of exhaust leaks. The compact, low-mass design also helps with thermal efficiency. Because it's a direct-fit converter, installation is straightforward with the proper tools – no cutting or welding is needed, and essential gaskets and hardware are included to simplify the job.

This converter is designed to meet or exceed Federal emissions requirements. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details on fitting this part to your vehicle.
