Product Details

The Walker Quiet-Flow SS line focuses on stainless-steel construction and direct-fit replacement geometry for vehicles that need a factory-style exhaust repair. Part number 55589 is an oval muffler assembly with a 16-inch body length, 11-inch body width, and 5.5-inch body height, built to match the original exhaust routing on the Toyota FJ Cruiser. This Walker 55589 muffler assembly is a practical choice when replacing a worn or noisy rear exhaust section on the 2007-2014 Toyota FJ Cruiser.

This part cross-references AP Exhaust (e.g., 7513, 54186) for the same application.

Common Problems It Can Address

• Exhaust noise from a damaged or rusted muffler
• Corrosion-related failure in the rear exhaust assembly
• Fitment issues from a non-OE replacement muffler
• Exhaust leaks at flange-connected joints
• Loss of factory-style exhaust routing on a Toyota FJ Cruiser

Installation Notes and Tips

Verify flange style, inlet configuration, outlet configuration, and overall length before installation. This muffler assembly uses a center inlet and offset outlet with 2-bolt welded flange connections, so the existing exhaust layout must match the vehicle application. Professional installation is recommended for proper alignment and sealing on the 2007-2014 Toyota FJ Cruiser.
