MagnaFlow Conv DF 2008 Buick Lucerene 3.8L

This is the MagnaFlow Direct-Fit Catalytic Converter, part number 51743, specifically made for your 2008 Buick Lucerne with the 3.8L engine. If your check engine light is on due to emissions issues, or if your old converter is failing, this part is designed to get your exhaust system back to proper working order and help you pass emissions tests. It's built to meet or exceed Federal EPA emissions requirements for OBDII vehicles registered in states with Federal/EPA emission systems.

MagnaFlow uses high-strength 16-gauge 409 stainless steel tubing for the construction, which offers excellent resistance to corrosion and ensures a long service life. The tubing is mandrel-bent to maintain the original equipment design and geometry, helping to replicate factory flow dynamics for consistent performance and fuel efficiency. The converter features a spun body design, and the single laser fusion weld is designed to greatly reduce the chance of leaks. This compact, low-mass design also contributes to better thermal efficiency. Because it's a direct-fit unit, installation is made simpler as it bolts directly in place of the original converter, meaning no cutting or welding is required. MagnaFlow includes the necessary gaskets to ensure a proper seal during installation.

When you're replacing a catalytic converter, it's important to have all the necessary components for a leak-free installation. This MagnaFlow converter comes with a crush ring gasket and a flange gasket, so you'll have what you need to get the job done right. Remember, this converter is designed for Federal/EPA emission systems and is not approved for sale or use in California.
