Detailed Description

Eastern Convertors 40461 is a replacement catalytic converter for the left side undercar position on 1998-2003 Mercedes-Benz ML320 vehicles. It is engineered as a Federal / EPA direct-fit unit with an ECO II catalyst and a 60-inch overall length, helping maintain the original exhaust layout on the listed application. The converter includes two oxygen sensor ports and uses a 2-bolt spinner inlet with a 2-bolt welded outlet for the specified connection style.

Manufacturing methods include automated workstations, spinner welding equipment, and high-speed production lines to maintain OE dimensions and fitment consistency. The NANO substrate chemistry is used to support efficient catalyst loading while keeping the converter cost-conscious for replacement use. This part number 40461 is a practical choice when replacing the original left undercar converter on a Mercedes-Benz ML320.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Failed or inefficient catalytic converter operation
• Exhaust emissions-related fault codes
• Restricted exhaust flow from a worn converter
• Rattling or damaged converter substrate
• Direct-fit replacement needs for the left undercar position

Installation Notes and Tips

Compatible With 1998-2003 Mercedes-Benz ML320, left undercar. Verify the vehicle is Federal / EPA equipped before ordering; this converter is not for sale or use in California, Colorado, Maine, or New York for vehicles with CA emissions. Confirm the inlet and outlet flange style, O2 sensor port count, and overall length before installation. Because inlet gasket quantity is listed as none and outlet gasket quantity is listed as two, inspect the existing exhaust sealing surfaces and replace worn sealing components as needed during service.

Quality Assurance

Eastern Convertors uses automated production methods and OE-dimension-focused manufacturing to support consistent fitment and repeatable build quality. The DIRECT FIT line is intended to provide a replacement converter that matches the listed Mercedes-Benz ML320 application with the specified connection and sensor layout.
