Detailed Description

AP Exhaust 644214 is a direct-fit catalytic converter for the left side of select Land Rover Discovery, Range Rover, and Range Rover Sport models. The Federal / EPA configuration and ceramic substrate support emissions-system replacement where the original converter has failed, triggered a check engine light, or no longer meets exhaust flow requirements. With two oxygen sensor ports and OE-style connection points, this unit is built to match the factory exhaust layout on the listed vehicles.

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

What It Is Used For

• Replacing a failed catalytic converter on the left side of the exhaust system
• Addressing catalyst-efficiency diagnostic trouble codes
• Restoring exhaust flow after internal substrate damage or restriction
• Correcting emissions-system issues on listed Land Rover models
• Returning the vehicle to a direct-fit exhaust configuration

Installation Notes and Tips

Verify the vehicle’s emissions configuration, left-side position, and sensor-port layout before installation. This converter uses a flare with spin flange inlet, a pipe outlet, and no included inlet or outlet hardware. Confirm the outlet size and exhaust routing against the original part before assembly.
