Product Details

The Eastern Convertors DIRECT FIT line is focused on replacement parts that match original equipment dimensions and installation points. This catalytic converter with integrated exhaust manifold is designed for the front right side of the Ram ProMaster exhaust system and follows the factory-style layout used on firewall-side and radiator-side applications depending on model year. Part number 20466 is a direct-fit solution for 2014-2021 Ram ProMaster 1500, 2500, and 3500 vans with Federal / EPA emissions configuration.

Manufacturing methods include automated workstations, spinner welding equipment, and high-speed production lines to maintain consistent fitment and dimensional accuracy. The ECO CARB catalyst type and proprietary NANO substrate chemistry are used to support efficient catalyst loading in a cost-conscious replacement design. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Part Helps Address

• Check engine light related to catalytic converter efficiency
• Failed emissions inspection caused by a worn or restricted converter
• Exhaust leaks at the manifold-to-pipe connection
• Cracked or damaged integrated manifold assembly
• Loss of exhaust flow from internal catalyst deterioration
