Product Details

If your check engine light is on and you suspect an emissions issue, this MagnaFlow Diesel Oxidation Catalyst is a solid option for your 2001-2006 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD. This converter is designed to meet Federal EPA emissions requirements, helping to ensure your truck stays compliant and the check engine light stays off. It's built to function like the original equipment, so you can expect it to fit and perform correctly.

Constructed from durable 16-gauge 409 stainless steel tubing, this converter is built to resist corrosion and last. MagnaFlow uses a single laser fusion weld, which is a strong way to join the pieces and helps prevent leaks. The compact, low-mass design also contributes to better thermal efficiency. While it's a universal fit, meaning it's adaptable to a range of vehicles, installation will require cutting and welding to integrate it into your exhaust system.

This converter is EPA-compliant for federal emissions systems, but it is not CARB approved and cannot be shipped to California. Make sure to check your vehicle's specific emissions system requirements before purchasing.
