Walker Quiet-Flow SS Muffler Assembly

Walker Quiet-Flow SS 50091 is a direct-fit exhaust muffler assembly built with stainless steel body and muffler construction for longer service life than typical aluminized replacements. It is shaped as an oval reflection muffler with a natural finish and OE-style pipe connection and tip outlet layout.

Compatible with select Ford Fusion and Lincoln MKZ applications, this muffler assembly is built for drivers replacing a worn or damaged rear exhaust component on a factory-style system. The Walker Quiet-Flow SS line focuses on stainless-steel construction and direct-fit replacement geometry for domestic and foreign vehicles.

What It Helps Address

Installation Notes and Tips

Verify inlet diameter, outlet configuration, and overall length against the existing exhaust before installation. This assembly uses a body-side inlet with pipe connection and dual tip outlets, so alignment with the vehicle’s exhaust routing is important. For welded assemblies, replace all required related parts during service to maintain proper fit and sealing. Confirm the vehicle year, make, and model match the listed applications before ordering.

Quality Assurance

Walker Quiet-Flow SS muffler assemblies use stainless-steel construction for improved durability compared with typical aluminized mufflers. The Quiet-Flow SS line is offered as a direct-fit OE-style replacement for domestic and foreign vehicles, and listed applications include premium fitment notes for select Ford Fusion and Lincoln MKZ models.
