Walker 48354 Exhaust Resonator and Pipe Assembly

Walker 48354 is an exhaust resonator and pipe assembly built for OE-style fit, sound, and flow. It is engineered with precise tuning to help maintain the original exhaust character on select Ford Taurus and Mercury Sable applications.

  • 2.25 in. inlet inside diameter and 2.25 in. outlet outside diameter
  • 87.5 in. overall length for application-specific exhaust routing
  • 18 in. round resonator body with 5 in. height and 5 in. width
  • Steel pipe and steel body construction
  • Aluminized finish for added corrosion resistance
  • Pipe connection inlet and outlet for direct exhaust system integration

OE-Style Exhaust Fit and Sound

This Walker 48354 resonator assembly is designed to match the original system’s fit, performance, and sound profile. The tuned resonator design supports smooth exhaust flow while helping preserve the factory sound level on vehicles such as the Ford Taurus and Mercury Sable. This part cross-references Walker Exhaust 21638 for the same application.

Vehicle Fitment

  • Fits 2010-2012 Ford Taurus, rear, with Federal Emission System; if welded assembly, replace all required parts.
  • Fits 2008-2009 Ford Taurus, with Federal Emission System; if welded assembly, replace all required parts.
  • Fits 2008-2009 Ford Taurus, with California Emission System; if welded assembly, replace all required parts.
  • Fits 2008-2009 Mercury Sable, with Federal Emission System; if welded assembly, replace all required parts.
  • Fits 2008-2009 Mercury Sable, with California Emission System; if welded assembly, replace all required parts.

Common Issues This Part Can Address

  • Exhaust noise from a worn or damaged resonator assembly
  • Restricted exhaust flow caused by internal deterioration
  • Fitment problems when replacing an OE-style resonator and pipe section
  • Corrosion-related exhaust leaks in the resonator area
  • Factory exhaust tone changes after system damage or repair

Installation Notes and Tips

Confirm emission system type before ordering, since fitment varies by Federal and California configurations. For welded assemblies, replace all required parts during service to maintain proper alignment and sealing. Verify inlet and outlet dimensions, overall length, and rear-position fitment against the existing exhaust layout before installation.

Quality Assurance

Walker uses precise tuning methods to help the resonator deliver OE-style sound and consistent flow characteristics. The aluminized steel construction is selected for durability in exhaust service, and the part is built to follow original-system fitment requirements for the listed Ford Taurus and Mercury Sable applications.
