AP Exhaust 641478 Catalytic Converter with Integrated Exhaust Manifold - Front Left or Left

Direct-Fit Manifold Converter for Ford and Lincoln

AP Exhaust 641478 is a direct-fit catalytic converter with integrated exhaust manifold for front left, radiator-side applications. It is built for specific Ford and Lincoln vehicles and uses a stainless steel body with a ceramic substrate for OE-style fitment and emissions control.

The AP Exhaust Direct Fit Converter w/ Manifold line focuses on exact dimensions and consistent installation fitment. For buyers searching for a Ford Explorer catalytic converter with manifold or a Lincoln MKX front left manifold converter, this part number 641478 is built to match the original layout.

• Restricted exhaust flow from a worn converter
• Check engine light concerns related to O2 sensor readings
• Fitment issues when replacing an OE manifold converter assembly

Installation Notes and Tips

Confirm the vehicle’s year, make, model, engine configuration, and emissions package before ordering AP Exhaust 641478. This unit uses an 8-bolt welded inlet flange, a 2-bolt welded outlet flange, and two O2 sensor ports, so sensor and flange alignment should be verified against the original assembly. This part cross-references Ford OE number DA8Z5G232C for the same application.

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 chemistry is used to support efficient catalyst loading and consistent converter performance across the AP Exhaust 641478 application range.
