Product Details

The AP Exhaust DHNXV02.4FB3 product line is built using proprietary substrate chemistry and advanced manufacturing methods to support consistent converter loading, OE-style dimensions, and repeatable fitment. AP Exhaust 771423 is part of that line and is intended for front catalytic converter replacement on California-emissions Honda Accord and Honda CR-V applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

For shoppers searching for a 2013-2016 Honda Accord front catalytic converter or a 2015-2016 Honda CR-V front catalytic converter, AP Exhaust 771423 provides a direct-fit replacement with the correct emissions certification details and factory-style connection points.

Common Problems This Part Addresses

• Failed catalytic converter emissions testing
• Check engine light related to catalyst efficiency
• Restricted exhaust flow from a worn converter
• Fitment issues caused by non-OE-style replacement parts
• Need for a California-compliant front converter replacement

Installation Notes and Tips

Verify the vehicle’s emissions label and EO requirements before installation. Confirm front-position placement, O2 sensor port location, and flange style against the original converter on the Honda Accord or Honda CR-V. Proper exhaust sealing and sensor transfer are important for accurate operation after installation.

Quality Assurance

AP Exhaust uses automated workstations, spinner welding equipment, and high-speed production lines to build converters to exact OE dimensions and fitment standards. The DHNXV02.4FB3 line is manufactured for consistent quality control and California emissions compliance.
