Overview

Walker EPA 70419 is a specific-fit catalytic converter built for EPA-compliant replacement on select OBDII vehicles. It uses a stainless steel body and a direct-fit layout to simplify exhaust service while maintaining the required emissions function.

Compatible with 2013-2017 Nissan Quest, rear, this catalytic converter is a fitment-based replacement for the exhaust system. The Walker EPA line focuses on compliant replacement parts for import and domestic applications, and part number 70419 is listed for this Nissan Quest application.

Key Features

• Stainless steel body for corrosion resistance in exhaust environments
• Round body design with welded flange connections
• EPA-compliant replacement for OBDII vehicles
• Walker EPA 70419 for verified application matching

Detailed Description

Walker EPA 70419 is engineered as a direct-fit catalytic converter for the exhaust system, with a 3-bolt welded inlet flange, 2-bolt welded outlet flange, and no O2 sensor ports. The round stainless steel body measures 8.000 inches long, 4.000 inches wide, and 4.000 inches high, with a 2.750-inch outlet outside diameter. For buyers searching for a catalytic converter for Nissan Quest rear exhaust service, this part number 70419 provides a specific application match rather than a universal fit.

The Walker EPA product line is positioned for EPA-standard replacement needs on 1996-and-newer OBDII vehicles. This makes it a practical choice when the original converter needs to be replaced with a compliant, direct-fit unit that follows the vehicle’s exhaust configuration. This part cross-references Nissan 200A04AY0A and 52702 for the same application.

What It Helps Solve

• Failed catalytic converter emissions testing
• Restricted exhaust flow from a worn converter
• Check engine light concerns related to converter performance
• Replacement needs for a damaged or corroded exhaust converter
• Fitment issues from using a universal exhaust part
