MagnaFlow Conv DF 03-07 GM 2500/3500 P/S OEM

If you're working on a 2003-2009 Chevrolet Express 2500 or 3500, or a similar GMC Savana, and need to replace the catalytic converter, this direct-fit unit from Magnaflow is a solid option. It's designed to meet Federal emissions requirements set by the EPA, which helps ensure your check engine light stays off and your vehicle passes emissions tests in most states. This converter is built to function just like the original equipment, so you can be confident it will fit and perform correctly.

Magnaflow builds this converter using 16-gauge 409 stainless steel tubing, which is known for resisting corrosion and lasting a long time. The tubing is mandrel-bent, meaning it's bent without kinking, which helps maintain smooth exhaust flow and keeps factory performance and fuel efficiency. They also use 308 stainless steel for the MIG welds, which are strong and durable. The design process involves 3D scanning to ensure it replicates the original equipment's fit and function precisely. This approach, along with a single laser fusion weld on the collector, helps reduce the chance of leaks and improves thermal efficiency.

Installation is made easier because this converter is a direct-fit design, meaning no cutting or welding is required if you have the proper tools. Magnaflow includes the necessary gaskets and hardware, like a flange gasket, a Torca clamp, and a crush ring gasket, so you won't have to reuse old, corroded factory parts. Just remember, this converter is EPA-compliant but not CARB approved, so it cannot be shipped to California.
