Walker Quiet-Flow SS Muffler Assembly

The Walker Quiet-Flow SS muffler assembly is a direct-fit OE-style replacement built for drivers who want a stainless-steel exhaust solution with a factory-style connection layout. Part number 55595 is listed for the right side on select Acura MDX applications and is built to match the original exhaust routing.

  • Stainless-steel muffler body and construction for improved corrosion resistance.
  • Direct-fit OE-style design for straightforward exhaust replacement.
  • Offset inlet and outlet pipe connections for application-specific fitment.
  • Oval combination muffler design with a regular-grade build.

Walker Quiet-Flow SS is the brand’s stainless-steel muffler line, focused on longer service life than typical aluminized mufflers. This part number 55595 uses a pipe-connection inlet and outlet, with a 2-inch inlet and a 2.25-inch outlet, making it a fit-focused choice for exhaust repair where the original muffler assembly has worn out or corroded. It fits 2007-2009 Acura MDX, right, and the interchange reference 18307STXA02 may be used for the same application.

Common Exhaust Issues It Can Address

  • Rust or corrosion in the muffler assembly.
  • Exhaust noise caused by a damaged internal muffler structure.
  • Restricted exhaust flow from a deteriorated replacement part.
  • Fitment problems when replacing a worn OE-style muffler assembly.

Installation Notes

Verify the vehicle’s right-side application, inlet and outlet configuration, and overall exhaust layout before installation. This muffler assembly uses pipe connections and an offset configuration, so matching the original routing is important for proper alignment. If the welded assembly is being replaced, inspect the related exhaust components and replace all required parts as needed.

Quality Assurance

Walker Quiet-Flow SS stainless-steel construction is positioned for longer life than typical aluminized mufflers. Part number 55595 is built as a direct-fit OE-style replacement for application-specific exhaust service.
