Walker EPA Product Line Details

Walker EPA converters are built for import and domestic OBDII vehicles and focus on direct-fit replacement geometry. This line is intended to simplify exhaust service by matching the original converter layout, connection style, and sensor placement for the listed applications.

Detailed Description

Walker 16779 is a front catalytic converter with a round stainless steel body, direct-fit configuration, and 2-inch outside diameter outlet. The unit measures approximately 18 inches overall and uses a 2-bolt welded flange at both the inlet and outlet for a secure exhaust connection. It is listed for front, radiator-side placement and is not CARB certified. For vehicles that require EPA federal-emissions equipment, this converter provides a replacement option that follows the original fitment pattern on applications such as the Dodge Grand Caravan, Dodge Journey, and Chrysler 200.

This part cross-references Dorman - OE Solutions 674-120 and Eastern Catalytic 20442 for the same application.

What It Helps Address

• Failed catalytic converter efficiency codes
• Exhaust restriction from a damaged or clogged converter
• Rattling or broken converter substrate
• Exhaust leaks at the front converter connection points
• Emissions-test failures on EPA federal-emissions vehicles
