Walker 55999 Exhaust Resonator and Pipe Assembly

Walker 55999 Exhaust Resonator Assembly

Walker 55999 is a welded exhaust resonator and pipe assembly built to match original-system fit, flow, and sound characteristics. It is a direct-fit exhaust replacement for Ram 1500 and Ram 1500 Classic applications with OE-style tuning.

Key Features

• Welded resonator assembly with precise tuning for OE-style exhaust sound.
• Aluminized steel body with steel piping for durable exhaust service.
• Oval body shape with offset inlet and angle-trimmed tailpipe outlet.
• 3.000-inch inlet and 3.000-inch outlet for matched exhaust routing.
• Hanger included for installation on the intended exhaust layout.

Detailed Description

Walker 55999 is engineered as an exhaust resonator and pipe assembly for Ram truck exhaust systems that need original-equipment style fit and acoustic control. The welded construction, oval resonator body, and tuned flow path help maintain exhaust routing while preserving the sound profile expected from the factory system. This part number, 55999, is a practical choice when replacing a worn or damaged resonator section on Ram 1500 and Ram 1500 Classic models.

Compatible With 2014-2017 Ram 1500 and 2019-2023 Ram 1500 Classic. This part cross-references 55398254AE for the same application.

What It Helps Address

• Exhaust noise changes caused by a damaged resonator assembly.
• Restricted exhaust flow from a corroded or failing pipe section.
• Fitment issues when replacing the factory resonator and pipe assembly.
• Loss of OE-style exhaust tone after the original part wears out.

Installation Notes and Tips

Verify inlet and outlet diameter, offset inlet layout, and overall length before installation. This assembly uses a pipe connection inlet and an angle-trimmed tailpipe outlet, so matching the existing exhaust routing is important. Mounting hardware is not included.

Quality Assurance

Walker designs this resonator assembly to fit, perform, and sound like the original system, with tuning focused on flow characteristics and OE-style acoustics.
