Magnaflow 19-20 GMC Sierra 1500 Single Underbody 4.3L/5.3L Direct Fit Catalytic Converter

MagnaFlow is well-known for its exhaust systems, and they bring that same attention to detail to their direct-fit catalytic converters. This 280656 model is designed to keep your check engine light off by meeting Federal/EPA emissions requirements for OBDII registered vehicles. It's built to fit a range of trucks, including the 2019-2023 Chevrolet Silverado 1500 and GMC Sierra 1500, as well as the 2021-2023 Tahoe and Yukon models.

This converter is constructed from high-strength 16-gauge 409 stainless steel tubing, which is great for resisting corrosion and ensuring a long service life. The mandrel-bent tubing helps maintain smooth airflow, replicating the original equipment's flow dynamics to keep your factory performance and fuel efficiency. MagnaFlow uses advanced 3D scanning during their design process to ensure this converter fits and functions just like the original part. The single laser fusion weld is designed to minimize the chance of exhaust leaks, and its compact, low-mass design also helps with thermal efficiency.

Installation is straightforward, as this is a direct-fit unit that doesn't require cutting or welding. You'll find a clamp and gaskets included in the box to help you get a proper seal and simplify the installation process. This converter is EPA-compliant for federal emissions systems but is not CARB approved, so it cannot be shipped to California.
