Walker Quiet-Flow SS Muffler Assembly

Walker Quiet-Flow SS 53620 is a direct-fit exhaust muffler assembly built for the rear right position on select Acura MDX models. It combines stainless-steel construction with an OE-style replacement layout to support longer service life than typical aluminized mufflers.

Compatible with 2004-2006 Acura MDX, rear right, this muffler assembly is shaped as an oval unit with an offset inlet and offset outlet tip for a factory-style exhaust repair. Walker 53620 is a practical choice when replacing a worn or noisy rear muffler on the Acura MDX.

Product Details

The Walker Quiet-Flow SS line focuses on stainless-steel construction and direct-fit replacement geometry for domestic and foreign vehicles. Part number 53620 follows that approach with an oval stainless-steel body, aluminized finish, and OE-style inlet and outlet placement to match the original exhaust routing on the 2004-2006 Acura MDX. The design supports a clean replacement for the rear right muffler assembly while maintaining factory-style fitment characteristics.

This part cross-references Hayden 2594 and 163-039 for the same application.

Common Repair Applications

  • Replacement for a rusted or corroded rear muffler assembly
  • Repair for exhaust noise caused by a damaged muffler body
  • Solution for exhaust leaks at the muffler connection area
  • Replacement for a bent, cracked, or worn rear right exhaust section
  • Factory-style restoration on 2004-2006 Acura MDX exhaust systems

Installation Notes

Verify the inlet diameter, outlet tip configuration, and rear right position before installation. This muffler assembly uses a pipe connection inlet and offset inlet/outlet layout, so the existing exhaust routing must match the vehicle application. If the original assembly was welded in place, replace all required related exhaust parts during service to ensure proper alignment and sealing.

Quality Assurance

Walker Quiet-Flow SS muffler assemblies are built with stainless-steel construction for improved durability compared with standard aluminized mufflers. Part number 53620 is engineered as a direct-fit OE-style replacement for the specified Acura MDX applications.
