MagnaFlow GM 3500/4500 HD 6.0L 3in Universal Converter

This Magnaflow OEM Grade Universal Catalytic Converter is designed to help keep your check engine light off and meet federal emissions standards. You get the converter itself, ready for installation. Because it's a universal fit, it requires cutting and welding to integrate into your exhaust system, making it a good option when a direct-fit replacement isn't available or cost-effective.

Built with high-strength 16-gauge 409 stainless steel tubing, this converter is made to resist corrosion and last a long time. The spun body construction features a single laser fusion weld, which greatly reduces the chance of leaks. Magnaflow designed this converter to replicate OEM flow dynamics, so you can expect factory-like performance and fuel efficiency. Its compact and lightweight design also contributes to better thermal efficiency and makes it easier to install in tight spaces.

This catalytic converter is EPA-compliant for Federal/EPA emission systems on OBDII registered vehicles. Please note that it is not CARB approved and cannot be shipped to California. If you're working on a 2015, or 2021-2023 Chevrolet Express 3500, or similar GM HD trucks like the Suburban 3500 HD or GMC Savana, this Magnaflow converter is a solid option for restoring emissions compliance.
