Product Details

If your 1999-2004 Ford Mustang GT's check engine light is on, it might be time to replace the catalytic converter. This direct-fit unit from Magnaflow is designed to get your emissions system back in compliance and keep that light off. It's built to meet or exceed federal emissions requirements for OBDII vehicles registered in states with California or Federal/EPA emission systems.

Magnaflow uses highly corrosion-resistant stainless steel tubing, including free-flowing mandrel-bent sections, to ensure this converter lasts and doesn't restrict exhaust flow. They use advanced 3D scanning during development to make sure it fits just like the original equipment, and the single laser fusion weld is designed to prevent leaks. This converter is designed for easy installation with the proper tools, as no cutting or welding is needed. You'll find everything you need to get it installed, including nuts, O2 port plugs, Torca clamps, and a flange gasket, all included in the box.

This converter is designed to interchange with OE part numbers like 2R3Z-5F250-DA and XR3Z-5F250-EGL. Please note that this converter is not CARB approved and cannot be shipped to California.
