Walker 54806 Exhaust Resonator and Pipe Assembly

Walker 54806 Exhaust Resonator Assembly

Walker 54806 is an exhaust resonator and pipe assembly built for OE-style fit, sound, and flow. It is engineered for the 2009-2010 Mercury Mariner and uses a tuned resonator design to help maintain factory-like exhaust tone.

With aluminized steel construction, a 16-inch resonator body, and a 40-inch overall length, this Walker exhaust resonator assembly is made for direct replacement service on the Mercury Mariner exhaust system. The 2-bolt welded flange inlet and 2.25-inch outlet outside diameter support a factory-style pipe connection.

Product Details

Walker 54806 is built to match the original exhaust system’s fit, sound, and flow characteristics as closely as possible. The resonator uses precise tuning to help control exhaust tone while supporting smooth exhaust flow, making it a practical replacement for a worn or damaged factory resonator on the Mercury Mariner. This part cross-references AP Exhaust 44924 for the same application.

Common Issues This Part Can Help Address

• Exhaust noise from a damaged resonator
• Rattling or corrosion in the factory exhaust section
• Loss of factory-style exhaust tone
• Restricted exhaust flow caused by internal deterioration
• Fitment problems from a failed original pipe assembly

Installation Notes

Verify the inlet flange style and 2.25-inch outlet connection before installation. Confirm vehicle application by year and model, since this part fits 2009-2010 Mercury Mariner, N/A. Inspect adjoining exhaust components, hangers, and sealing surfaces during replacement to help ensure a proper exhaust seal and alignment.

Quality Assurance

Walker designs this resonator assembly to follow OE-style fitment and sound targets, with tuning intended to support factory-like exhaust performance on the Mercury Mariner. The aluminized steel construction is selected for exhaust-system service in a replacement application.
