MagnaFlow Conv DF 99/01-03 Ford Mustang 3.8L

This MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter, part number 444063, is built with highly corrosion-resistant stainless steel and features free-flowing mandrel-bent tubing. It's designed to keep your check engine light off and ensure your 1999-2004 Ford Mustang with a 3.8L or 3.9L engine meets emissions standards, especially in California and other CARB-restricted states.

MagnaFlow uses advanced 3D scanning systems during their research and development process to ensure this converter fits and functions just like the original equipment. The single laser fusion weld is designed to significantly reduce the chance of leaks, and its compact, low-mass design contributes to greater thermal efficiency. The precision-stamped collector design helps optimize exhaust flow, which can maintain factory performance and fuel economy. Installation is straightforward, with no cutting or welding required, making it a manageable DIY project with the proper tools.

This catalytic converter is specifically designed to meet or exceed California Air Resource Board requirements. It has undergone additional testing to comply with CARB guidelines, making it legal for use in California and other states with strict emissions regulations. The package includes two O2 port plugs to help complete the installation.
