Magnaflow 16-17 Cadillac ATS 2.0L Close Coupled Direct Fit Converter

When your check engine light comes on for emissions issues, you need a reliable replacement for your catalytic converter. This Magnaflow Direct-Fit Catalytic Converter, part number 21-408, is designed to keep your 2016-2020 Chevrolet Camaro, 2016-2019 Cadillac ATS, or 2016-2019 Cadillac CTS compliant with Federal/EPA emissions standards. It's built to meet or exceed these requirements for OBDII Federally registered vehicles, ensuring your car runs cleanly and legally.

What you get in the box is a complete kit for installation: the converter itself, a flange gasket, a flange ring, two nuts, and two bolts. Magnaflow uses high-strength 16-gauge 409 stainless steel tubing for excellent corrosion resistance, meaning it's built to last. The design replicates the original equipment's flow dynamics, helping maintain factory performance and fuel efficiency. Installation is made simpler because it's a direct-fit unit, meaning no cutting or welding is required, just proper tools. The single laser fusion weld is designed to greatly reduce the chance of leaks, and its compact, low-mass construction also contributes to better thermal efficiency.

This converter is EPA-compliant and designed to keep your check engine light off. It's important to note that this converter is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific tool requirements and procedures.
