Direct-Fit Catalytic Converter for Ford Trucks

AP Exhaust 645911 is a Federal / EPA direct-fit catalytic converter built for specific Ford F-150 and Ford F-250 applications. It uses a stainless steel body, a ceramic substrate, and OE-style dimensions to support proper exhaust fitment on the listed trucks.

Key Features

  • Federal / EPA direct-fit catalytic converter
  • Stainless steel body for exhaust system durability
  • Ceramic substrate material
  • 2-bolt loose flange inlet with female flare on both inlet types
  • 2.25" OD pipe outlet
  • 1 O2 sensor port
  • 58.5-inch overall length
  • OE-dimensioned construction for listed Ford F-150 and Ford F-250 applications

Detailed Description

AP Exhaust 645911 is engineered for Ford F-150 and Ford F-250 trucks that require a direct-fit catalytic converter replacement. The stainless steel body and ceramic substrate are paired with AP Emissions Technologies manufacturing methods that focus on consistent dimensions, fitment accuracy, and efficient converter construction. This part number is a practical choice for owners searching for a Ford F-150 catalytic converter replacement or a Ford F-250 direct-fit exhaust repair.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

  • Restoring exhaust flow after converter restriction or damage
  • Addressing emissions-related fault codes tied to converter performance
  • Repairing exhaust leaks at the converter connection points

Installation Notes

Verify the inlet style, outlet size, O2 sensor port location, and overall length before installation. Some Ford F-250 applications note that air tube kit 4948 may be required. Review the emissions notes carefully, since this converter is listed for Federal and California emissions configurations but is not for sale or use on vehicles licensed in CA, CO, ME, or NY.

Quality Assurance

AP Exhaust uses proprietary substrate chemistry and automated manufacturing processes to build converters to exact OE dimensions and fitment. That production approach supports consistent installation on the listed Ford F-150 and Ford F-250 applications.
