Walker 47839 Exhaust Resonator and Pipe Assembly

Walker 47839 Exhaust Resonator and Pipe Assembly

Walker 47839 is an exhaust resonator and pipe assembly engineered for OE-style fit, flow, and sound control. It is built for 2006-2009 Subaru Legacy and 2006-2009 Subaru Outback applications, with aluminized steel construction and welded flange connections for a direct replacement layout.

For Subaru Legacy and Subaru Outback owners looking for a replacement resonator assembly, this part number 47839 follows the original system’s tuning approach to help restore factory-like exhaust tone and routing.

Detailed Description

Walker 47839 is designed to match the original exhaust system’s fit, performance, and sound characteristics. The resonator uses tuned internal design to support smooth exhaust flow while helping maintain OE-style sound quality on Subaru Legacy and Subaru Outback models from 2006 through 2009. The aluminized steel construction and welded flange ends support a durable replacement for the factory resonator and pipe assembly.

This part cross-references AP Exhaust 48713 and BRExhaust 286-975 for the same application.

Common Replacement Reasons

• Exhaust noise that has become louder or more resonant than factory levels
• Rust or corrosion on the resonator or pipe section
• Cracks, leaks, or separation at the flange connections
• Damaged exhaust routing on a Subaru Legacy or Subaru Outback
• Need to restore OE-style exhaust tone after component failure

Installation Notes and Tips

Verify flange style, overall length, and vehicle application before installation. This assembly uses a 2-bolt welded flange inlet and outlet, so matching the existing exhaust connection points is important for proper alignment. Inspect adjoining exhaust components, gaskets, and hangers for wear before completing the repair.

Quality Assurance

Walker designs this resonator assembly to follow original-system tuning principles and OE-style sound characteristics. The aluminized steel body and pipe construction are selected for everyday exhaust service in Subaru Legacy and Subaru Outback applications.
