MagnaFlow Conv DF 03-06 Lincoln LS 3.9L

If your Lincoln LS's check engine light is on, especially if it's related to emissions, it might be time to replace the catalytic converter. This direct-fit unit from Magnaflow is built to keep your 2003-2006 3.9L LS running cleanly and legally. It's designed to meet or exceed federal emissions requirements, so you can be confident it'll pass inspection and keep that warning light off.

Magnaflow uses high-strength 16-gauge 409 stainless steel tubing for the body, which means it's going to resist corrosion and last a long time. The tubing is mandrel-bent, which helps maintain consistent flow without restrictions, just like the original part. They also use durable 308 stainless steel for the MIG welds, and their single laser fusion weld design greatly reduces the chance of leaks. Magnaflow's research team uses 3D scanning to ensure this converter fits and functions exactly like the factory original, making installation straightforward. You won't need to cut or weld anything; it bolts right up.

This converter comes with two Torca Accuseal clamps, which are designed to provide a secure, even seal all the way around. It's a solid option for getting your Lincoln LS back into emissions compliance. Just a heads-up, this converter is EPA-compliant but not CARB approved, so it cannot be shipped to California.
