Detailed Description

AP Exhaust 644170 is part of the Direct Fit Converter line, which is engineered around OE dimensions and fitment consistency. The converter uses ARISTO substrate chemistry and modern manufacturing methods to support efficient converter loading while keeping the part aligned with factory-style exhaust geometry. For buyers searching for a Ford Edge catalytic converter, Ford Fusion catalytic converter, or Lincoln MKZ catalytic converter, this part number is built for the listed direct-fit applications.

This part cross-references Ford F2GZ-5F250-B for the same application.

What It Helps Solve

Failed catalytic converter efficiency codes.
Exhaust restriction caused by a worn converter core.
Emissions test failures on supported vehicles.
Fitment issues from using a non-direct replacement.
Corrosion-related exhaust replacement needs.

Installation Notes and Tips

Verify the vehicle’s emissions configuration and listed position before ordering. Some fitments note welded OE assemblies or use with aftermarket components, so compare the existing exhaust layout to the application notes. This converter has no O2 sensor ports and uses a 2-bolt flange inlet with a 2.36-inch OD outlet.

Quality Assurance

AP Exhaust states that the Direct Fit Converter line is manufactured to exact OE dimensions and fitment using automated production equipment and spinner welding processes. That production approach supports consistent part geometry for the listed applications.
