MagnaFlow 2009 Chevrolet Express 4500 V8 6.0L Left Underbody Catalytic Converter

If you're working on a 2009 Chevrolet Express 4500 or a 2009 GMC Savana 4500 with the 6.0L V8 engine, this MagnaFlow Direct-Fit Catalytic Converter is what you need to keep your exhaust system running cleanly and efficiently. This part is designed to replace the original left underbody converter, ensuring your vehicle meets federal emissions standards and keeps that check engine light off. It's built to be a direct replacement, meaning no cutting or welding is required for installation, making the job much simpler with the right tools.

MagnaFlow uses high-strength 16-gauge 409 stainless steel for the tubing, which is great for resisting corrosion and ensuring a long service life, especially under the vehicle. The tubing itself is mandrel-bent to maintain consistent diameter and smooth airflow, just like the factory setup, which helps keep your engine running efficiently. They also use durable 308 stainless steel for the MIG welds, and the single laser fusion weld on the converter body itself is designed to minimize the chance of exhaust leaks. The compact, low-mass design also helps with thermal efficiency. MagnaFlow's metrology department uses 3D scanning to ensure this converter fits and functions precisely like the original equipment it replaces.

This converter is designed to meet or exceed EPA emissions requirements for OBDII federally registered vehicles. It includes a crush ring gasket and a Torca clamp to help you get a solid seal during installation. Please note that this converter is not CARB approved and cannot be shipped to California.
