Product Details

This is the MagnaFlow HM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter, part number 93671, specifically made for the 1999-2004 Ford Mustang GT with the 4.6L engine. If your check engine light is on due to emissions issues, this converter is designed to help get your Mustang back into compliance and running smoothly. It's built to meet or exceed Federal emissions requirements set forth by the EPA for OBDII Federally registered vehicles.

MagnaFlow uses advanced 3D scanning during their research and development to ensure this converter fits and functions just like the original equipment. The tubing is mandrel-bent to maintain consistent diameter and eliminate flow restrictions, which helps keep exhaust flowing freely. It's constructed from highly corrosion-resistant stainless steel, with durable 308 stainless steel MIG welds and OE-sized hangers made from 410 stainless steel, all designed for a long service life. The single laser fusion weld is designed to greatly reduce the possibility of leaks, and its compact, low-mass design also contributes to better thermal efficiency.

Installation is made straightforward because this is a direct-fit unit, meaning no cutting or welding is required if you have the proper tools. MagnaFlow includes essential hardware like a flange gasket, nuts, O2 port plugs, and Torca clamps to make the job easier. This converter interchanges with several OE part numbers, including 2R3Z-5F250-DA and XR3Z-5F250-EGL.
