What makes this catalytic converter CARB compliant?

This Magnaflow catalytic converter has undergone additional testing to comply with California Air Resource Board (CARB) guidelines. This ensures it meets or exceeds emissions requirements for legal use in California and other states with strict emissions regulations.

Does this catalytic converter require welding to install?

No, this is a direct-fit catalytic converter designed to bolt on directly to your existing exhaust system. No cutting or welding is required for installation, and it includes the necessary gaskets for a proper seal.

What is the benefit of the spun body design and laser fusion weld?

The OE-style spun body design, combined with a single laser fusion weld, greatly reduces the possibility of exhaust leaks. This construction method helps ensure a reliable and leak-free seal for the catalytic converter.

This converter is built with free-flowing, mandrel-bent tubing and uses a corrosion-resistant stainless steel construction for a long service life. Magnaflow uses advanced 3D scanning to ensure the part fits just like the original equipment, and the OE-style spun body design with a single laser fusion weld helps prevent exhaust leaks. Its compact, low-mass design also contributes to better thermal efficiency. Because it's a direct-fit converter, installation is straightforward with no cutting or welding needed, and it includes the necessary gaskets for a proper seal.

This Magnaflow converter is designed to meet or exceed CARB requirements, and it interchanges with original equipment part numbers 18 30 7 592 437 and 18 30 7 553 825. Make sure you have the proper tools for installation, as it's a bolt-on replacement.
