Product Details

Walker Quiet-Flow SS 21456 is built for drivers replacing a worn or damaged muffler on a Jeep Wrangler without changing the factory-style exhaust layout. The stainless-steel body, oval shape, and welded flange inlet support a clean installation on the listed applications, while the 2.25-inch outlet sizing matches the specified exhaust connection. This part cross-references Anchor 2396 and Flosser 2248 for the same application.

Compatible With 2000 Jeep Wrangler, N/A and 2001-2006 Jeep Wrangler, N/A. The part number 21456 is also useful when verifying the correct Walker Quiet-Flow SS muffler for these Wrangler fitments.

Common Replacement Reasons

  • Rusted or perforated muffler body
  • Exhaust noise that is louder than normal
  • Restricted exhaust flow from internal deterioration
  • Failed welded joints or damaged inlet/outlet connections
  • Need for an OE-style replacement muffler on a Jeep Wrangler

Installation Notes

Verify inlet and outlet configuration before installation: center inlet, offset outlet, 2-bolt welded flange inlet, and 2.25-inch outlet inside diameter. This muffler is not reversible and is not tunable, so orientation should match the vehicle’s exhaust routing. If the exhaust assembly is welded, replace all required related parts during service to ensure proper alignment and sealing.

Quality Assurance

Walker Quiet-Flow SS mufflers are built with stainless-steel construction and are positioned as precision-fit replacement parts with OE-style sound characteristics. Confirmed fitment includes 2000 Jeep Wrangler and 2001-2006 Jeep Wrangler applications.
