Quiet-Flow SS Muffler Assembly

Walker Quiet-Flow SS 53981 is a direct-fit exhaust muffler assembly built for select Kia Optima applications. It uses stainless steel construction and an OE-style layout to match the original exhaust routing while providing a corrosion-resistant replacement option.

  • Stainless steel body and muffler construction for improved corrosion resistance.
  • Direct-fit OE-style replacement for select Kia Optima exhaust systems.
  • Oval reflection muffler design with offset inlet and offset outlet configuration.
  • Natural finish with pipe connection inlet and tip-style outlet.
  • Part number 53981 for application matching and catalog lookup.

Quiet-Flow SS is Walker’s stainless-steel muffler line focused on direct replacement fitment and longer service life than typical aluminized mufflers. This muffler assembly is engineered for the right-side exhaust position on 2011-2018 Kia Optima models listed in the fitment data, including 2017-2018 Kia Optima, right, and 2011-2016 Kia Optima, right. The part number 53981 also cross-references Walker Exhaust 53980 for the same application.

Common Exhaust Issues It Can Address

  • Rust damage in the muffler body or internal structure.
  • Exhaust noise caused by a worn or failing muffler assembly.
  • Fitment problems from a damaged or non-original exhaust replacement.
  • Corrosion-related exhaust deterioration in exposed underbody conditions.

Installation Notes

Verify inlet diameter, outlet configuration, and overall length against the original exhaust before installation. Fitment data lists right-side applications only, and some 2011-2016 Kia Optima listings note exceptions for Korean-built vehicles. If the exhaust uses a welded assembly, replace all required related parts during service.

Quality Assurance

Walker states that Quiet-Flow SS uses the only broad-market stainless-steel construction in this product family and is offered as a direct-fit OE-style replacement. Part number 53981 is built for the listed Kia Optima applications and is supported by Walker’s Quiet-Flow SS product line positioning.
