Magnaflow 05-09 Ford Mustang 4.6L Direct Fit Converter

For 2005-2009 Ford Mustang owners dealing with a failing catalytic converter, this MagnaFlow direct-fit unit (part number 5461001) is a CARB-compliant replacement that bolts into the factory location without cutting or welding. Whether your Mustang has thrown a P0420 efficiency code or you need to pass an emissions inspection, this converter is legal in all 50 states and drops right in.

MagnaFlow builds this converter with 16-gauge 409 stainless steel tubing and mandrel bends that replicate the OE exhaust path. The spun body design with a laser fusion weld keeps the assembly tight and leak-resistant, and MagnaFlow's 3D scanning process during development ensures the fitment matches the original part precisely. Two Torca AccuSeal exhaust clamps are included, providing 360-degree clamping force at both connections without distorting the pipe.

The converter interchanges with Ford OE parts 4R3Z-5F250-C, 4R3Z-5F250-GA, and 4R3Z-5F250-GB, covering the S197 Mustang platform across GT and V8 applications with the 4.6L engine. Hardware comes in the box along with the clamps, so the installation stays clean without reusing corroded factory fasteners. If you want a straightforward catalytic converter replacement that meets emissions standards and fits the way the factory part did, this is the piece.
