• Specific-fit exhaust resonator and pipe assembly for Ram 2500 and Ram 3500
• 3.500-inch inlet inside diameter and 3.500-inch outlet outside diameter
• 63.160-inch overall length with oval steel body construction
• Welded hanger included for factory-style mounting
• Premium-grade replacement built to follow original exhaust routing
• Single inlet, single tailpipe outlet configuration

Detailed Description

This Walker resonator assembly is engineered for 2014-2018 Ram 2500 and 2014-2018 Ram 3500 trucks that use a specific-fit exhaust layout. The oval steel body measures 12.000 inches long, 9.750 inches wide, and 4.250 inches high, with a welded hanger and pipe connection inlet for a direct-style replacement. Walker 56321 is designed to deliver the flow characteristics and sound profile expected from an original-equipment-style exhaust resonator and pipe assembly.

This part cross-references Mopar 68213395AB for the same application. If you are replacing a worn or damaged resonator on a Ram 2500 or Ram 3500, part number 56321 provides a direct-fit solution that follows the factory exhaust path.

What It Helps Address

• Exhaust noise changes caused by a damaged resonator
• Rust or corrosion in the factory resonator and pipe section
• Fitment issues from a bent or failing exhaust assembly
• Loss of OE-style exhaust tone after replacement work
• Need for a direct replacement on Ram 2500 and Ram 3500 trucks

Installation Notes and Tips

Verify inlet and outlet diameter, overall length, and hanger location against the original part before installation. This assembly is not reversible and does not include mounting hardware or a gasket or seal. Because it uses a welded hanger and specific-fit configuration, it should be matched to the factory exhaust routing on the vehicle.

Quality Assurance

Walker designs this resonator assembly to fit, perform, and sound like the original system, using tuning methods intended to support OE-style exhaust flow and sound characteristics. Part number 56321 is built as a premium replacement for select Ram applications.
