Detailed Description

Walker Quiet-Flow 54939 is an exhaust muffler assembly engineered for Ford Fiesta models and built to match OE-style replacement requirements. The round stainless steel body uses a reflection muffler design to support controlled exhaust sound while maintaining a direct-fit layout for the listed Fiesta applications. This part number is a practical choice when replacing a worn or damaged muffler assembly on a 2011-2019 Ford Fiesta, including 2011-2016 Ford Fiesta Premium and Limited trim applications noted in the fitment data. Walker 54939 also cross-references AP Exhaust 40023 for the same application.

What It Helps Address

  • Exhaust noise from a damaged or deteriorated muffler assembly
  • Rust or corrosion in the muffler body
  • Loss of factory-style exhaust tone on a Ford Fiesta
  • Fitment issues caused by a previous non-OE-style exhaust repair
  • Replacement needs for a welded assembly where required parts must be addressed

Installation Notes and Tips

Compatible With 2011-2016 Ford Fiesta, N/A, and 2017-2019 Ford Fiesta, N/A. The inlet uses a pipe connection with an offset configuration, and the outlet uses dual tips with dual outlets. Verify inlet and outlet dimensions, overall length, and body dimensions against the existing exhaust layout before installation. If the vehicle uses a welded assembly, replace all required related parts during service to ensure proper fit and sealing.

Quality Assurance

Walker Quiet-Flow muffler assemblies are positioned as OE-style replacement parts with broad coverage for domestic and foreign vehicles. The stainless steel construction and direct-fit design support consistent replacement quality for the listed Ford Fiesta applications.
