Magnaflow 12-20 Chevrolet Express 4500 Underbody 6.0L Direct Fit Catalytic Converter

The stainless steel construction on this Magnaflow catalytic converter is a key detail, offering solid resistance to corrosion and a longer service life, especially important for a part exposed to the elements underneath your vehicle. This converter is designed specifically for your 2012-2020 Chevrolet Express 3500, aiming to keep your check engine light off and ensure your vehicle meets Federal emissions requirements set by the EPA. It’s built to function just like the original equipment, using advanced 3D scanning during its design process to ensure a precise fit and proper exhaust flow.

You can install this converter yourself without needing to cut or weld, thanks to its direct-fit design. The included gaskets and hardware make the job smoother, avoiding the need to reuse old, potentially corroded factory parts. The mandrel-bent tubing helps eliminate flow restrictions, maintaining the performance and fuel efficiency you expect from your Express 3500. Magnaflow also uses a single laser fusion weld, which helps reduce the chance of leaks, and its compact, low-mass design contributes to better thermal efficiency.

This Magnaflow catalytic converter is a well-built replacement part that complies with legal standards for OBDII Federally registered vehicles. While it meets federal emissions standards, please note it is not CARB approved and cannot be shipped to California.
