MagnaFlow Conv DF 03-04 Exped 4.6L Driver Side OEM

This is the Magnaflow direct-fit catalytic converter for the driver's side of your 2003 or 2004 Ford Expedition with the 4.6L engine. If your check engine light is on due to a failing converter, or if you're replacing a damaged one, this part is designed to get your Expedition back to running cleanly and efficiently.

Magnaflow builds this converter using 16-gauge 409 stainless steel tubing, which is known for resisting corrosion and lasting a long time. The tubing itself is mandrel-bent to ensure smooth airflow, helping to maintain factory performance and fuel economy. They use 308 stainless steel for the MIG welds, which are strong and help prevent leaks. Magnaflow also uses 3D scanning during their design process to make sure this converter fits just like the original equipment, so installation should be straightforward with no cutting or welding required, and they include the necessary gaskets and hardware to complete the job.

This converter is EPA-compliant and designed to meet federal emissions requirements for OBDII vehicles. It's a solid option for replacing your original converter and ensuring your Expedition passes emissions tests. Please note that this converter is not CARB approved and cannot be shipped to California.
