Detailed Description

Walker EPA 16489 is a direct-fit catalytic converter for the right-side exhaust position on select 2004-2015 Nissan Titan, 2005-2015 Nissan Armada, 2004-2010 Infiniti QX56, and 2004 Nissan Pathfinder Armada applications. It is engineered as a replacement converter for vehicles originally equipped with federal emissions systems, and the fitment notes specify that it is not legal for sale or use in California and other CARB-compliant states. This part cross-references AP Exhaust 642115 for the same application.

For buyers searching for a catalytic converter for a 2004-2015 Nissan Titan right side or a 2005-2015 Nissan Armada right side, this Walker EPA 16489 unit provides the correct direct-fit configuration with welded flange connections and a round stainless steel body. The product line is positioned for import and domestic OBDII vehicles, with a focus on emissions-system replacement rather than universal adaptation.

What It Helps Address

• Failed catalytic converter efficiency codes
• Restricted exhaust flow from a worn converter
