Walker Quiet-Flow SS Muffler Assembly

Walker Quiet-Flow SS 54560 is a direct-fit exhaust muffler assembly built for the 2004-2009 Toyota Prius. It combines stainless-steel muffler construction with an OE-style replacement layout to support longer service life than typical aluminized mufflers.

For Prius owners searching for a replacement exhaust muffler assembly, Walker 54560 offers a round, offset-inlet/offset-outlet design with a welded 2-bolt flange inlet and tip-style outlet. The Quiet-Flow SS line is Walker’s stainless-steel muffler family for domestic and foreign vehicles, focused on fitment and durability.

  • Round muffler shape with 7-inch body diameter

Detailed Description

Walker 54560 is an exhaust muffler assembly engineered as a direct-fit replacement for the Toyota Prius. It uses stainless steel for the muffler and body, helping provide greater corrosion resistance than standard aluminized mufflers. The round body measures 7 inches in diameter and 19 inches in body length, with a 46.5-inch overall length for OE-style routing.

This part features a 1.5-inch inlet with a 2-bolt welded flange, plus a 1.5-inch offset outlet with a tip-style end. If you are replacing a worn Prius muffler and want a stainless-steel OE-style exhaust solution, Walker 54560 is built for that application. This part cross-references AP Exhaust 7541 and BRExhaust 279-423 for the same application.

What It Helps Address

  • Exhaust noise from a damaged or rusted muffler
  • Corrosion-related muffler failure on a Toyota Prius
  • Exhaust leaks at the muffler connection point
  • Fitment issues from non-OE-style replacement parts
  • Replacement needs for a worn rear exhaust section

Installation Notes and Tips

Fits 2004-2009 Toyota Prius, N/A. Confirm inlet and outlet orientation, flange style, and overall length against the original exhaust before installation. Because this is an OE-style muffler assembly, matching the factory routing and hanger locations is important for proper alignment.

Walker 54560 is a practical choice when replacing the Prius muffler with a stainless-steel assembly that follows the original exhaust layout. Verify the vehicle’s existing exhaust configuration before ordering to ensure the correct fit.

Quality Assurance
