Detailed Product Overview

This Dorman catalytic converter, part number 679-522, is made for 2009-2020 Nissan Maxima rear exhaust applications. The cylinder-style body uses a stainless steel housing and ceramic substrate to support standard replacement service where the original converter has failed, become restricted, or no longer meets emissions-related performance requirements. The flanged inlet and outlet, along with the attached heat shield, help simplify replacement on the specified vehicle platform. This part cross-references Walker Exhaust 16701 for the same application.

Common Problems This Part Can Address

  • Check engine light related to catalytic converter efficiency
  • Restricted exhaust flow from a worn or damaged converter
  • Exhaust odor caused by converter deterioration
  • Failed emissions inspection on the listed Nissan Maxima applications
  • Noise or rattling from a deteriorated converter substrate

Installation Notes and Tips

Verify rear-position fitment before installation on 2009-2020 Nissan Maxima models. Confirm flange alignment, sensor port location, and gasket surfaces before assembly. Because this converter is not CARB certified, it is not intended for California-compliant applications. Use the included gaskets and hardware as specified during installation, and inspect adjoining exhaust components for wear or leakage before completing the repair.
