Product Details

Starting with the highly corrosion resistant 409 stainless steel tubing, this MagnaFlow catalytic converter is built to last. Specifically designed for the 1999-2001 Ford Mustang with the 3.8L engine, this direct-fit unit ensures you can keep your check engine light off and comply with emissions standards, even in California and other CARB-restricted states.

The engineers at MagnaFlow use advanced 3D scanning systems to replicate the original equipment's design and geometry. This means you get a part that fits right and functions as expected, without needing to cut or weld. The mandrel-bent tubing is key here, as it maintains a consistent diameter throughout, eliminating flow restrictions and helping to preserve your vehicle's fuel economy. The single laser fusion weld is also a notable detail, significantly reducing the chance of exhaust leaks and contributing to the converter's overall thermal efficiency.

This converter is designed to meet or exceed California Air Resource Board (CARB) requirements, making it a legal replacement in states with strict emissions regulations. It includes the necessary gaskets and hardware for installation, simplifying the process for a DIY-friendly job when you have the proper tools. You can be confident that this part will interchange with OE parts like YR3Z-5F250-AA and YR3Z-5F250-SGL.
