Magnaflow Conv DF 07-08 Buick Lucerne 3.8L

If your check engine light is on and you suspect a catalytic converter issue on your 2006-2008 Buick Lucerne with the 3.8L engine, this direct-fit replacement from Magnaflow is a solid option. It's built to meet Federal emissions requirements, helping you pass inspections and keep your car running cleanly. Magnaflow uses advanced scanning technology during development to ensure this converter matches the original equipment's fit and function, so you can be confident it will work right on your vehicle.

This converter is constructed with strong 16-gauge 409 stainless steel tubing, which holds up well against corrosion and should give you a long service life. The tubing is mandrel-bent to maintain the original design and geometry, and the body replicates the OE spun design. A single laser fusion weld is used to greatly reduce the chance of exhaust leaks, and its compact, low-mass design helps with thermal efficiency. Because it's a direct-fit unit, installation is made simpler as it bolts right up without needing any cutting or welding, and it includes the necessary gaskets for a proper seal.
