Magnaflow 16-17 Cadillac CT6 3.0L Direct Fit Converter

When it's time to replace the catalytic converter on your 2016-2019 Cadillac CT6 with the 3.0L engine, Magnaflow's Direct-Fit Catalytic Converter 21-914 is a solid option. This unit is designed to meet or exceed Federal emissions requirements set forth by the EPA, ensuring your vehicle remains compliant with legal standards for OBDII Federally registered vehicles. It's built to keep that check engine light off and your exhaust system functioning correctly.

What you get in the box is a well-built converter that uses free-flowing, mandrel-bent tubing constructed from highly corrosion-resistant stainless steel. Magnaflow uses advanced 3D scanning during their research and development to ensure this part fits and functions just like the original equipment. The OE-style spun body design is paired with a single laser fusion weld, which significantly reduces the chance of exhaust leaks. This compact, low-mass design also contributes to greater thermal efficiency. Installation is made simpler because it's a direct-fit unit, meaning no cutting or welding is required, and it includes the necessary gaskets and hardware for a proper seal.

This converter interchanges with several OE part numbers, including 12689673 and 12668677, making it a straightforward replacement. Just remember that this converter is EPA-compliant and not CARB approved, so it cannot be shipped to California.
