Magnaflow 16-17 Cadillac CT6 3.0L Direct Fit Converter

When your Cadillac CT6's catalytic converter needs replacing, Magnaflow's Direct-Fit Catalytic Converter (part number 21-915) is built to get you back on the road with confidence. This converter is specifically designed for the 2016-2019 Cadillac CT6 with the 3.0L engine, aiming to keep your check engine light off and ensure your vehicle meets federal emissions requirements. It's engineered to be a direct replacement, meaning no cutting or welding is needed for installation, making it a job you can often tackle yourself with the right tools.

What you get in the box is a well-built converter featuring free-flowing, mandrel-bent tubing made from high-strength 16-gauge 409 stainless steel for excellent corrosion resistance and a long service life. Magnaflow uses advanced 3D scanning to ensure the fit and function match the original equipment, replicating the OE spun body design. This design, along with a single laser fusion weld, helps prevent leaks and offers greater thermal efficiency. The package also includes essential gaskets and hardware, so you have what you need for a proper seal and a straightforward installation.

This converter is designed to meet or exceed Federal emissions requirements set forth by the EPA for OBDII Federally registered vehicles. While it's EPA compliant, please note it is not CARB approved and cannot be shipped to California. It interchanges with OE parts 12668678 and 12673972.
