Walker 21442 Exhaust Resonator for Ram HD

Walker 21442 is a direct OE replacement exhaust resonator built for 1998-2002 Dodge Ram 2500 and 1998-2002 Dodge Ram 3500 applications. It uses aluminized steel construction and center pipe connections to match the original exhaust layout and sound profile.

Key Features

• Direct OE replacement for factory-style exhaust service
• Fits 1998-2002 Dodge Ram 2500 and 1998-2002 Dodge Ram 3500
• Aluminized steel body for corrosion resistance in exhaust service
• Round resonator design with center inlet and center outlet
• 3-inch inlet inside diameter with pipe connection ends
• Walker part number 21442 for catalog and cross-reference use

Product Details

Walker 21442 is an exhaust resonator designed to follow the original system’s fit, flow characteristics, and OE-style sound. The round steel body measures 14 inches in body length with a 6-inch body width and 6-inch body height, giving it the proportions needed for factory-style exhaust routing on Ram HD trucks. This resonator is a practical choice for owners looking for a replacement that maintains the original exhaust path on a Dodge Ram 2500 or Dodge Ram 3500.

This part cross-references Monroe Shocks & Struts (e.g., 38917) for the same application.

Common Issues It Can Address

• Exhaust resonance or drone from a worn resonator
• Rust damage in the original aluminized exhaust component
• Loss of factory exhaust tone after system wear
• Fitment problems when replacing a damaged OE resonator
• Need for a direct replacement on Ram 2500 and Ram 3500 exhaust systems

Installation Notes and Tips

Verify inlet and outlet orientation before installation. Walker 21442 uses center inlet and center outlet pipe connections, so the replacement should be matched to the existing exhaust routing on the vehicle. Confirm the 3-inch inlet inside diameter and overall dimensions against the original resonator before welding or clamping into place.

Quality Assurance

Walker resonators are engineered to match original-system fit, performance, and sound characteristics using precise tuning methods and OE-style construction standards.
