Walker 31539 Exhaust Pipe Flange Gasket

Walker 31539 is an exhaust pipe flange gasket built for a 2-bolt flange connection. It uses fiber with a steel core to help maintain a tight seal at the exhaust joint, and its dimensions are sized for the specified port and bolt pattern. This gasket is a direct-fit style option for 2004 Subaru Legacy and Outback with 3 catalytic converter, as well as 2005 Subaru Legacy and Outback SULEV applications.

Detailed Description

Walker 31539 is made for exhaust repair work where the flange connection needs a precise sealing surface. The fiber material with steel core helps the gasket hold shape at the joint, while the 2-bolt layout and listed dimensions support proper alignment at the exhaust pipe flange. For Subaru Legacy and Subaru Outback models in the listed years, this gasket matches the specified exhaust configurations and supports a clean seal at the connection point. This part cross-references Monroe Shocks & Struts (e.g., 13886-1, EG24466) for the same application.

Common Repair Uses

  • Exhaust leak at the flange connection
  • Noise from a damaged or worn gasket surface
  • Loss of sealing after exhaust service
  • Replacement during catalytic converter or pipe repair
  • Fitment correction for Subaru Legacy and Outback exhaust joints

Installation Notes and Tips

Confirm the flange pattern, bolt hole spacing, and port dimensions before installation. Clean both mating surfaces thoroughly so the gasket seats evenly, and inspect the flange for warping or corrosion that could affect sealing. Use the listed fitment details to verify the correct Subaru Legacy or Subaru Outback application before assembly.

Quality Assurance

Walker supplies exhaust sealing components for OE exhaust systems and Walker aftermarket replacement parts, with a focus on fitment and serviceable sealing performance. Part number 31539 is built to match the listed exhaust flange specifications for the confirmed Subaru applications.
