Detailed Description

Walker Quiet-Flow SS 53966 is engineered as a replacement muffler assembly for the Volvo XC90, covering 2007-2014 model years. The stainless-steel body and muffler construction help resist corrosion better than standard aluminized designs, while the OE-style layout supports a cleaner replacement on the original exhaust path. The body-side inlet, 2.375-inch inlet diameter, and dual 3-inch outlets make this a fitment-specific solution for drivers replacing a worn or damaged rear muffler assembly on the Volvo XC90.

Part number 53966 follows that approach with a combination muffler assembly built around factory-style dimensions and outlet configuration. This part cross-references Four Seasons 54922 for the same application.

Common Problems This Part Can Address

  • Exhaust leaks caused by a damaged muffler body

  • Poor fitment after prior exhaust repairs or welded modifications
  • Need for a direct-fit replacement on a 2007-2014 Volvo XC90

Installation Notes and Tips

Verify inlet and outlet dimensions against the existing exhaust before installation. Because this is a direct-fit OE-style replacement, alignment with the original exhaust routing is important for proper fit. If the welded assembly has been modified or repaired previously, inspect the surrounding exhaust sections and replace all required parts before installation. Confirm the vehicle is a 2007-2014 Volvo XC90 before ordering part number 53966.
