What It Is Used For

  • Replacing a damaged or rusted left-side resonator and pipe assembly
  • Restoring factory-style exhaust sound on GMC Acadia dual-exhaust systems
  • Correcting exhaust leaks caused by corrosion or cracked tubing
  • Replacing a worn OE resonator section on 2013-2016 GMC Acadia and 2017 GMC Acadia Limited
  • Maintaining proper exhaust routing after factory system wear or damage

Installation Notes and Tips

Verify left-side placement and dual-exhaust configuration before ordering. This assembly uses a pipe connection inlet and spout outlet, so confirm the existing exhaust layout and connection style on the vehicle. If the original system is a welded assembly, replace all required related parts during service to ensure proper alignment and sealing.

Quality Assurance

Walker designs this resonator assembly to match original-system fit, performance, and sound characteristics using precise tuning methods for OE-style exhaust operation.
