Direct-Fit Catalytic Converter

AP Exhaust 645118 is a direct-fit catalytic converter built for a precise exhaust replacement on compatible Ford truck applications. It uses a stainless steel body, a ceramic substrate, and a Federal / EPA direct-fit design for straightforward service on emissions-related exhaust repairs.

Key Features

• Federal / EPA direct-fit converter for a factory-style exhaust replacement
• Stainless steel body for corrosion resistance in exhaust service
• Ceramic substrate for emissions control performance
• Two O2 sensor ports for sensor-equipped exhaust systems
• 2-bolt loose flange inlet with spherical flare connection
• 2.50-inch OD pipe outlet with outlet hardware included

Fitment Details

Fits 2011-2014 Ford F-150, left. This AP Exhaust catalytic converter is listed for Federal and California emissions applications and is a direct fit converter for the specified truck platform. AP Exhaust 645118 is built for the left-side exhaust position on these Ford F-150 model years.

What It Helps Address

• Failed catalytic converter emissions testing
• Restricted exhaust flow from a worn converter
• Check engine light concerns related to catalyst efficiency
• Exhaust leaks at the converter connection points
• Replacement needs for a damaged or corroded exhaust converter

Installation Notes

Verify the vehicle’s emissions configuration and sensor layout before installation. This converter uses a spherical flare loose flange inlet, a pipe outlet, and does not require an inlet gasket. Confirm the left-side application and the 2 O2 sensor port layout against the original part before service.
