AP Exhaust 58550 Muffler Assembly for Equinox and Terrain

AP Exhaust 58550 is an exhaust muffler assembly built with aluminized steel for corrosion resistance and dependable exhaust service. It is a direct-fit replacement for select 2010-2017 Chevrolet Equinox and 2010-2017 GMC Terrain applications with a welded OE-style exhaust layout.

Key Features

  • Aluminized steel muffler material for durable exhaust system service
  • Exhaust muffler assembly for OE-style replacement
  • Fits 2010-2017 Chevrolet Equinox, N/A
  • Fits 2010-2017 GMC Terrain, N/A
  • Part number 58550 for application matching and catalog lookup

Detailed Description

AP Exhaust 58550 is engineered for vehicles that use a welded factory exhaust assembly, making it a practical replacement for worn or damaged muffler sections on the Chevrolet Equinox and GMC Terrain. The aluminized steel construction helps resist exhaust-system corrosion while maintaining the fit and function expected in a direct replacement part. This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

What It Helps Address

  • Exhaust noise from a damaged or deteriorated muffler assembly
  • Rust-related failure in the factory welded exhaust section
  • Leaks caused by cracks, holes, or separated welds
  • Loss of exhaust system integrity on Equinox and Terrain models
  • Replacement needs for a welded OE exhaust configuration

Installation Notes and Tips

Fits 2010-2017 Chevrolet Equinox, N/A. Fits 2010-2017 GMC Terrain, N/A. Because the OE system was a welded assembly, the notes recommend replacing all listed related parts during service. Verify the vehicle’s exhaust layout and compare the existing assembly before installation. Part number 58550 should be matched to the exact application shown in the fitment data.

Quality Assurance

AP Exhaust manufactures exhaust components for replacement use, and this muffler assembly is built from aluminized steel to support long-term service in exhaust applications. Confirm fitment by year, make, and model before ordering.
