OE-Style Fit and Sound

Walker 55180 is engineered for Subaru Legacy exhaust repair where original sound quality and flow characteristics matter.

Common Issues This Part Can Address

  • Exhaust noise from a cracked or rusted resonator assembly

  • Corrosion-related failure in the resonator body or pipe
  • Leakage at worn 2-bolt flange connections
  • Restricted exhaust flow caused by internal deterioration

Installation Notes

Verify vehicle fitment before installation: Fits 1998-1999 Subaru Legacy, excluding GT Series. Confirm flange alignment, pipe routing, and overall length against the original exhaust assembly before welding or bolting in place. Because this unit uses 2-bolt welded flanges, proper gasket and fastener condition should be checked during installation.
