MagnaFlow Conv DF 03-09 GM 2500/3500 Driver Side

If your check engine light is on and you suspect a failing catalytic converter on your 2003-2009 Chevrolet Express 2500 or 3500, or GMC Savana 2500 or 3500, this direct-fit converter from Magnaflow is a solid option. It's built to meet Federal emissions requirements, so you can be confident it will help you pass emissions testing and keep that warning light off.

Magnaflow builds this converter with a spun body design, similar to the original equipment, which uses a single laser fusion weld to greatly reduce the chance of exhaust leaks. The tubing is mandrel-bent for consistent flow, and the whole unit is constructed from corrosion-resistant stainless steel, specifically 16-gauge 409 stainless steel for the tubing and 308 stainless steel for the welds, ensuring it holds up over time. The compact, low-mass design also helps with thermal efficiency. Magnaflow uses 3D scanning during development to ensure this converter fits and functions just like the factory part, making installation straightforward. Since it's a direct-fit design, you won't need to cut or weld anything; it bolts right up using the included hardware.

This converter comes with the necessary gaskets and hardware, including Torca AccuSeal exhaust clamps and an O2 port plug, to help you get a proper seal and complete the installation. Just remember that this converter is EPA-compliant and not CARB approved, so it cannot be shipped to California.
