Detailed Product Overview

Catco part number 9018 is engineered for direct replacement in 1998 Dodge B1500, B2500, and B3500, as well as 1999-2003 Dodge Ram 1500 Van, Ram 2500 Van, and Ram 3500 Van applications.

Common Problems This Part Can Address

Failed emissions testing caused by a worn or inefficient catalytic converter
Check engine light concerns related to catalyst efficiency codes
Exhaust restriction from a deteriorated converter substrate
Rust or corrosion damage to the original converter housing
Fitment issues when replacing a converter with a non-OE-style unit

Installation Notes and Tips

Verify the vehicle’s emissions configuration and confirm the listed 48-3/4" converter length before installation. This converter uses a 2-bolt loose flange inlet with female flare connections and a 2.50" OD pipe outlet, so matching the existing exhaust layout is important for proper installation. Outlet hardware is included; inlet gasket and inlet hardware are not included. Because fitment is specific, confirm the application by year, model, and emissions requirements before ordering.

Catco uses proprietary substrate chemistry and advanced manufacturing methods, including automated workstations, spinner welding equipment, and high-speed production lines, to build converters to OE dimensions and fitment standards. This production approach supports consistent converter construction and competitive pricing across the listed applications.

Compatible with 1998 Dodge B1500, B2500, and B3500, plus 1999-2003 Dodge Ram 1500 Van, Ram 2500 Van, and Ram 3500 Van applications. Catco 9018 is a direct-fit catalytic converter for these Dodge van exhaust repairs.
