Walker 54842 Exhaust Resonator and Pipe Assembly

Walker 54842 is an exhaust resonator and pipe assembly built for the 2008-2015 Scion xB. It uses steel construction with an aluminized finish and OE-style tuning to match original system sound and flow characteristics.

Key Features

  • Fits 2008-2015 Scion xB, N/A
  • Part number 54842 for direct application lookup
  • Steel pipe and steel resonator body for exhaust system durability
  • Aluminized finish for added corrosion resistance
  • 2-bolt welded flange inlet and spout outlet configuration
  • Overall length: 44.125 in.; muffler body length: 12 in.
  • Outlet outside diameter: 2.25 in.

Detailed Description

Walker 54842 is engineered as an OE-style exhaust resonator and pipe assembly for the Scion xB. The resonator body measures 12 inches long with a round 5 x 5 inch profile, and the assembly uses precise tuning to support original-equipment sound levels and steady exhaust flow. If you are replacing a worn or damaged exhaust section on a 2008-2015 Scion xB, part number 54842 provides the correct fitment format for that application.

This part cross-references AP Exhaust 7546 for the same application.

Common Issues This Part Can Address

  • Exhaust noise from a damaged resonator section
  • Rust or corrosion in the pipe or body
  • Fitment problems caused by a bent or failing exhaust assembly
  • Loss of OE-style exhaust tone after replacement
  • Restricted exhaust flow from a deteriorated resonator assembly

Installation Notes and Tips

Verify the inlet flange style, outlet diameter, and overall length before installation. This assembly uses a 2-bolt welded flange inlet and a spout outlet, so matching the existing exhaust connection points is important for proper alignment on the Scion xB. Check surrounding hangers, clamps, and adjoining exhaust components for wear before final installation.

Quality Assurance

Walker designs this resonator to fit, perform, and sound like the original system, using tuning methods aimed at OE-style exhaust characteristics and consistent flow.
