AP Exhaust 645246 Catalytic Converter - Right

AP Exhaust 645246 Catalytic Converter

AP Exhaust 645246 is a Federal / EPA direct-fit catalytic converter built for exact OE dimensions and fitment. It is engineered for the right side of select Ford F-150 applications and uses AP Emissions Technologies substrate chemistry to support efficient emissions control with controlled manufacturing consistency.

Key Features

• Federal / EPA direct-fit and direct-fit undercar design
• Fits right-side exhaust applications on select Ford F-150 models
• Overall length: 45.375 in. / 45.38 in.
• 2-bolt loose flange inlet and outlet configurations
• 2.5 in. ID pipe inlet type A
• 1 or 2 O2 sensor ports, depending on application
• Inlet and outlet gaskets not required
• AP Exhaust part number 645246

Fitment Details

• Fits 2009-2010 Ford F-150, right, Direct Fit; (4.6L, VIN 8, 24 Valve Eng., 4WD); Federal and California Emissions. Not For Sale or Use on vehicles licensed in the state of CA, CO, ME & NY. Restrictions may apply in other states. Check with your state authority for details.
• Fits 2009-2010 Ford F-150, right, Direct Fit; Federal and California Emissions. Not For Sale or Use on vehicles licensed in the state of CA, CO, ME & NY. Restrictions may apply in other states. Check with your state authority for details.

What It Helps Address

• Failed or inefficient catalytic converter operation
• Exhaust emissions concerns during inspection
• Check engine light conditions related to catalyst efficiency
• Fitment issues from non-direct replacement converters
• Exhaust system mismatch at the right-side converter location

Installation Notes

Verify engine, emissions package, and right-side placement before installation. This converter uses 2-bolt loose flange connections and does not require inlet or outlet gaskets. Confirm O2 sensor port count and pipe interface against the vehicle’s original exhaust layout before assembly. AP Exhaust 645246 is intended for direct-fit replacement on the listed Ford F-150 applications.

Quality Assurance

AP Exhaust uses automated workstations, spinner welding equipment, and high-speed production lines to build converters to OE dimensions and fitment standards. The ARISTO substrate formulation is used to support efficient catalyst loading and consistent converter performance. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
