Magnaflow Conv DF 2010-2011 LaCrosse 3.6 L Underbody

If your 2010 or 2011 Buick LaCrosse with the 3.6L engine is showing a check engine light related to emissions, it might be time to replace the catalytic converter. This direct-fit unit from Magnaflow is designed to get your vehicle running cleanly again and help you pass emissions testing.

Magnaflow builds this converter using 16-gauge 409 stainless steel tubing, which is known for resisting corrosion and lasting a long time. The tubing is mandrel-bent to maintain the original flow characteristics, so your engine should perform and maintain fuel efficiency like it did when it was new. They've replicated the OE spun body design, and the single laser fusion weld is a strong point that greatly reduces the chance of leaks. This compact design also helps with thermal efficiency. Because it's a direct-fit unit, installation is made simpler, with no cutting or welding needed. Magnaflow includes the necessary gaskets and hardware, so you won't have to reuse old, corroded parts or make a separate trip to the parts store.

This catalytic converter is designed to meet or exceed Federal emissions requirements set by the EPA for OBDII vehicles. Please note that this converter is not CARB approved and cannot be shipped to California.
