Fitment and Application Details

Compatible with 2005-2008 Honda Pilot and 2003 Acura MDX. Fits 2005-2008 Honda Pilot, N/A, and fits 2003 Acura MDX, N/A. This Walker 56172 resonator assembly is a fitment-based replacement for vehicles that use the listed welded-style exhaust configuration.

This part cross-references AP Exhaust 7677 and MAHLE 55469 for the same application.

What This Part Helps Address

  • Exhaust resonance or drone from a worn resonator assembly
  • Rust or corrosion damage in the resonator and pipe section
  • Cracked or leaking welded exhaust connections
  • Reduced exhaust flow caused by internal deterioration
  • Noise changes from a damaged OE-style exhaust component

Installation Notes and Tips

Verify the inlet flange style, outlet connection, and overall dimensions before installation. Because some applications use a welded assembly, replace all required related exhaust parts as needed to complete the repair. Confirm vehicle fitment by year, make, and model before ordering.

Quality Assurance

Walker designs this resonator assembly to follow original-system tuning principles, with attention to fit, flow, and OE-style sound characteristics. The aluminized steel construction supports long-term exhaust service in standard replacement applications.
