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's likely time to replace the catalytic converter. This direct-fit unit from Magnaflow is built to get your LaCrosse back to running cleanly and legally.

Magnaflow designed this converter to be a straightforward replacement for your original equipment. It uses free-flowing, mandrel-bent tubing made from strong 16-gauge 409 stainless steel, which resists corrosion and should last a long time. The body design mimics the factory unit for efficient thermal performance, and a single laser fusion weld helps prevent leaks. Magnaflow uses advanced 3D scanning during development to ensure this converter fits precisely and functions like the original, so you can be confident in its performance and compatibility. Installation is made easier because it 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. Always refer to the manufacturer's installation instructions for proper tool requirements and procedures.
