Product Details

Walker Quiet-Flow SS 21752 is a stainless-steel exhaust muffler for drivers seeking a direct replacement on select Ford F-150 trucks. The oval body, offset inlet, and offset outlet support factory-style routing, while the 2.75-inch pipe connections match the listed application requirements. This part number 21752 is part of Walker’s Quiet-Flow SS line, which is positioned around fit accuracy, exhaust flow, and a sound level that stays close to original equipment behavior. It also cross-references Ford OE numbers BL3Z5230B and BL3Z5230E for the same application.

What It Helps Address

  • Rust or corrosion in the original muffler housing
  • Exhaust noise caused by a worn internal muffler structure
  • Restricted exhaust flow from a deteriorated muffler
  • Fitment issues when replacing a factory-style Ford F-150 muffler
  • Need for a stainless-steel replacement on 2011-2020 Ford F-150 applications

Installation Notes

Confirm the vehicle year and exhaust configuration before ordering. This muffler uses pipe connections with a 2.75-inch inlet and outlet, plus offset inlet and outlet placement, so alignment with the existing exhaust path matters during installation. For welded assemblies, replace all required related exhaust parts as specified for the vehicle application. Fits 2020 Ford F-150, N/A. Fits 2011-2019 Ford F-150, N/A.

Walker Quiet-Flow SS mufflers are built from stainless steel and are designed for broad-market OE-style replacement use on domestic and import vehicles. Part Number 21752 is listed for specific Ford F-150 applications and follows Walker’s Quiet-Flow SS construction and fitment standards.
