What This Converter Helps Address

• Failed or inefficient rear catalytic converter performance
• California emissions compliance concerns
• Exhaust restriction caused by a damaged converter
• Check engine light conditions related to catalyst efficiency
• Fitment issues from non-direct replacement parts

Installation Notes

Verify the rear position and California emissions application before installation. This converter uses a 2-bolt welded inlet and a 2.25" OD pipe outlet, so matching the existing exhaust configuration is important for proper alignment. For 2001-2005 Ford Escape and Mazda Tribute rear applications, confirm the EO D-665-23 requirement and compare the OE reference numbers listed in the fitment notes.

This part cross-references Eastern Manufacturing, Inc. (e.g., 3FMXT03.01F7) for the same application.

Quality Assurance

AP Exhaust builds this converter with automated workstations, spinner welding equipment, and high-speed production lines to maintain OE-style dimensions and consistent fitment. The ARISTO substrate chemistry is used to support efficient catalyst loading and converter performance while keeping the unit CARB compliant under Executive Order D-665-23.
