MagnaFlow California Grade CARB Compliant Converter Direct Fit 11-14 Ford Mustang GT 5.0L

Running a 2011-2014 Ford Mustang GT 5.0L with a failing catalytic converter means dealing with check engine lights and potential emissions test failures. This MagnaFlow direct-fit converter is built for the S197 Mustang GT's Coyote 5.0L engine, and it bolts into position using the factory mounting points with no cutting or welding required.

MagnaFlow used 3D scanning during development to match the OEM exhaust geometry, which is especially important on a Mustang where the exhaust routing runs tight under the tunnel. The mandrel-bent 16-gauge 409 stainless steel tubing keeps exhaust flowing smoothly, and the spun body design paired with a single laser fusion weld minimizes leak potential along the seams. All joints use 308 stainless steel MIG welds, and the precision-stamped collector supports consistent flow through the converter body.

In the box, MagnaFlow includes 2 flange gaskets and 2 Torca AccuSeal clamps. The AccuSeal clamps provide full 360-degree clamping force to seat the converter evenly, and the fresh gaskets mean you will not have to reuse your old corroded hardware. This converter meets California Air Resources Board emissions standards, so it is legal in all 50 states. Confirm your Mustang's Executive Order number and Engine Family Number before installation.
