MagnaFlow Conv DF 03-04 Lincoln Navigator 5.4L P/S

When your 2003 or 2004 Lincoln Navigator needs a new catalytic converter, this direct-fit unit from Magnaflow is designed to get you back on the road legally and efficiently. You'll receive the catalytic converter itself, along with a Torca clamp and OE-sized exhaust hangers, so you have the essential hardware to complete the installation without needing to cut or weld your existing exhaust system. This setup is specifically made to keep your check engine light off and ensure your vehicle meets Federal emissions requirements.

Magnaflow builds this converter using a high-strength 16-gauge 409 stainless steel tubing for excellent corrosion resistance, meaning it's built to last. The internal design features mandrel-bent tubing to maintain consistent diameter and eliminate flow restrictions, helping your engine breathe freely and maintain its original performance and fuel economy. They also use a precision-stamped collector and a single laser fusion weld, which helps prevent leaks and contributes to the converter's thermal efficiency. Magnaflow uses advanced 3D scanning during their design process to ensure this part fits and functions just like the original equipment.

This converter is designed to meet or exceed EPA emissions standards for OBDII Federally registered vehicles. 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 proper fitment and any specific tool requirements.
