Eastern Convertors 20465 Catalytic Converter with Integrated Exhaust Manifold - Front Left

Direct-Fit Catalytic Converter Manifold for Ram ProMaster

Eastern Convertors DIRECT FIT Part Number 20465 is a catalytic converter with integrated exhaust manifold built for direct replacement on select Ram ProMaster vans. It uses a Federal / EPA direct-fit manifold design with OE-style dimensions to support proper alignment on the radiator side front-left exhaust location.

Key Features

• Part Number 20465 for direct-fit exhaust replacement
• Catalytic converter with integrated exhaust manifold
• Federal / EPA direct-fit manifold configuration
• Standard catalyst type
• 2-bolt welded flange inlet and outlet
• 18-inch overall length
• Built using automated production and spinner welding processes for OE dimension control
• NANO substrate chemistry for efficient catalyst loading

Product Details

Eastern Convertors DIRECT FIT is the brand line focused on OE-style fitment and consistent installation geometry. This converter manifold is engineered for 2014-2021 Ram ProMaster 1500, Ram ProMaster 2500, and Ram ProMaster 3500 applications in the front left, radiator side position. Part Number 20465 is built to match the original exhaust layout and flange style, helping maintain correct connection points during replacement.

The manufacturing process uses automated workstations, spinner welding equipment, and high-speed production lines to hold exact OE dimensions. The catalyst uses proprietary NANO substrate chemistry to support efficient loading and converter performance in a cost-conscious replacement part.

Vehicle Fitment

• Fits 2019-2021 Ram ProMaster 1500, front left, radiator side; not for sale or use in CA/NY & Maine vehicles with CA emissions.
• Fits 2019-2021 Ram ProMaster 2500, front left, radiator side; not for sale or use in CA/NY & Maine vehicles with CA emissions.
• Fits 2019-2021 Ram ProMaster 3500, front left, radiator side; not for sale or use in CA/NY & Maine vehicles with CA emissions.
• Fits 2014-2018 Ram ProMaster 1500, front left, radiator side; not for sale or use in CA, CO, ME & NY vehicles with CA emissions.
• Fits 2014-2018 Ram ProMaster 2500, front left, radiator side; not for sale or use in CA, CO, ME & NY vehicles with CA emissions.
• Fits 2014-2018 Ram ProMaster 3500, front left, radiator side; not for sale or use in CA, CO, ME & NY vehicles with CA emissions.

Common Replacement Uses

• Replacement for a cracked or leaking exhaust manifold and converter assembly
• Correction for exhaust leaks at the flange connection
• Replacement for a restricted or failed catalytic converter
• Repair for exhaust noise from the front-left radiator-side manifold area
• Direct replacement when OE manifold geometry no longer seals properly

Installation Notes

Verify the vehicle’s emissions configuration before ordering, since this part is restricted in certain states for vehicles with CA emissions. Confirm the front-left, radiator-side location and the 2-bolt welded flange connection points before installation. Use the existing exhaust routing and mounting points to match the OE layout on Ram ProMaster 1500, Ram ProMaster 2500, and Ram ProMaster 3500 models.

Quality Assurance

Eastern Convertors uses automated manufacturing, spinner welding, and high-speed production lines to maintain OE dimensions and fitment consistency. The NANO substrate chemistry is used to support efficient catalyst loading and reliable converter construction. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
