Magnaflow 07-08 Hummer H3 3.7L Direct Fit Converter

If you're looking to replace the catalytic converter on your 2007 or 2008 Hummer H3 with the 3.7L engine, this direct-fit unit from Magnaflow is built to meet California's strict emissions standards. It's designed to keep your check engine light off and ensure your vehicle passes emissions tests, especially in California and other CARB-restricted states. This converter is crafted to replicate the original equipment's flow dynamics, meaning you won't lose factory performance or fuel efficiency.

What sets this converter apart is its construction and ease of installation. It uses high-strength 16-gauge 409 stainless steel tubing for excellent corrosion resistance, so it's built to last. The welds are durable 308 stainless steel MIG welds, and Magnaflow uses a single laser fusion weld that significantly reduces the chance of leaks. Because it's a direct-fit design, you won't need to cut or weld anything; it bolts right up to your existing exhaust system using the included donut gasket. Magnaflow uses advanced 3D scanning during their research and development to ensure a precise fit, just like the original part.

This converter is specifically designed to comply with California Air Resource Board (CARB) requirements, meaning it's legal for sale and installation in California and other states that follow its emissions guidelines. You'll receive the converter and the necessary donut gasket to help make your installation straightforward.
