MagnaFlow Conv DF 01-04 Century 3.1L/Impala

If your 1997-2005 Buick Century's check engine light is on and you suspect the catalytic converter, this Magnaflow Direct-Fit converter is a solid option. It's built to meet Federal emissions requirements, helping you pass inspections and keep that light off. Magnaflow uses advanced scanning to ensure this converter fits just like the original equipment, so you won't have to fight with it during installation.

This converter is made with strong 16-gauge 409 stainless steel tubing for good corrosion resistance, and the body is designed to be thermally efficient. The single laser fusion weld helps prevent leaks, and the mandrel-bent tubing maintains the factory flow dynamics. Because it's a direct-fit design, installation is straightforward – no cutting or welding is needed, and it even comes with the necessary gaskets and hardware to avoid reusing old, corroded parts.
