- 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.
