Walker Quiet-Flow SS Muffler

The Walker Quiet-Flow SS muffler, part number 21244, is a specific-fit exhaust replacement built for drivers who want stainless-steel construction and OE-style sound control. It fits 2016-2018 Kia Sorento, front, and uses a precision-fit design for straightforward exhaust service.

Key Features

  • 100% stainless-steel body for corrosion resistance.

  • Specific-fit construction for a direct application match.
  • Oval body shape with a welded 2-bolt flange outlet.

Detailed Description

Walker Quiet-Flow SS 21244 is engineered as a premium exhaust muffler with a stainless-steel body, pipe-connection inlet, and center outlet layout. The oval case measures 16.000 inches long, 11.000 inches wide, and 5.500 inches high, with a 2.500-inch inlet inside diameter and a 2.495-inch outlet outside diameter. For Kia Sorento exhaust repair, this muffler provides a fit-focused replacement that maintains factory-like sound characteristics while improving flow through a stainless construction.

Quiet-Flow SS is Walker’s stainless-steel muffler line for buyers who want a durable exhaust solution with OE-style acoustics. Part number 21244 is also referenced as 21-150 in Cardone Reman listings and 28600C6100 in interchange data for the same application.

What It Helps Solve

  • Rust-through or corrosion in the muffler body.
  • Exhaust noise that has become louder than factory levels.
  • Restricted exhaust flow from a worn internal design.
  • Fitment issues when replacing a specific Kia Sorento muffler.

Installation Notes and Tips

This muffler includes a hanger, and clamps are not included. Verify the vehicle application and exhaust routing on the 2016-2018 Kia Sorento before final assembly.

Quality Assurance

Walker positions Quiet-Flow SS as a stainless-steel muffler line with precision fit and OE-style sound characteristics. Part number 21244 is built for specific-fit exhaust replacement service.
