AP Exhaust 645402 Catalytic Converter - Right
Direct-Fit Catalytic Converter for Ford Trucks
AP Exhaust 645402 is a Federal / EPA direct-fit catalytic converter built for specific Ford Expedition and Ford F-150 applications. It uses a stainless steel body, a ceramic substrate, and OE-style dimensions to support proper fitment on the right side of the exhaust system.
For 1997-2000 Ford F-150 and 1999-2000 Ford Expedition applications, this converter is built to match the original mounting and connection style. AP Exhaust 645402 is engineered for direct replacement service where a right-side catalytic converter is required.
Key Features
- Federal / EPA direct-fit catalytic converter
- Stainless steel body for exhaust system durability
- Ceramic substrate material
- 2-bolt loose flange inlet with spherical flare
- 2.50" ID inlet and 2.50" OD pipe outlet
- 2 O2 sensor ports
- 47-inch overall length
- Outlet hardware included; inlet and outlet gaskets not required
Fitment Details
- Fits 1999-2000 Ford Expedition, right; direct fit; 4.6L 4WD on select applications; Federal and California Emissions.
- Fits 1999-2000 Ford Expedition, right; direct fit; Federal and California Emissions.
- Fits 1998-2000 Ford F-150, right; direct fit; 4.6L on select applications; Federal and California Emissions.
- Fits 1997-2000 Ford F-150, right; direct fit; Federal and California Emissions.
- Fits 1997 Ford F-150, right; direct fit; 4.6L 4WD; Federal and California Emissions.
How It Works
This catalytic converter is built to replace the original right-side unit on select Ford Expedition and Ford F-150 trucks. AP Exhaust 645402 uses proprietary substrate chemistry and modern manufacturing methods to support efficient catalyst loading while maintaining OE dimensions and fitment. The result is a direct replacement that aligns with the factory exhaust layout and sensor placement.
Common Problems It Can Address
- Failed emissions testing from a worn or inefficient catalytic converter
- Check engine light concerns related to catalyst efficiency
- Exhaust restriction caused by a deteriorated substrate
- Rust or corrosion damage to the original converter body
- Fitment issues when replacing a damaged right-side converter
Installation Notes
Verify engine size, drive configuration, emissions type, and right-side placement before installation. This part uses a 2-bolt loose flange inlet with a spherical flare, a 2.50" ID inlet, and a 2.50" OD pipe outlet. Two oxygen sensor ports are provided, and outlet hardware is included. Inlet gasket, inlet hardware, and outlet gasket are not required.
For California, Colorado, Maine, and New York registration use, review local emissions rules before purchase. Confirm the vehicle’s emissions label and underbody layout against the listed fitment for 1997-2000 Ford F-150 and 1999-2000 Ford Expedition applications.
Quality Assurance
AP Exhaust uses automated workstations, spinner welding equipment, and high-speed production lines to build converters to exact OE dimensions and fitment. Part number 645402 is manufactured to support consistent installation and repeatable replacement performance for the listed Ford applications.
