Detailed Description

Walker Quiet-Flow SS 54877 is an exhaust muffler assembly engineered as a direct-fit replacement for the left side of select Nissan Maxima vehicles. The stainless steel body and muffler materials help provide longer service life than common aluminized mufflers, while the OE-style configuration supports a cleaner factory-type repair. This part number is also referenced as Walker 54877 for catalog and search purposes.

The Quiet-Flow SS line focuses on stainless-steel replacement mufflers for domestic and foreign vehicles, and this application follows that approach with an oval body, reflection muffler type, 11-inch body diameter, 11-inch body width, 5.5-inch body height, and 12-inch body length. The inlet uses a 2-bolt welded flange with an offset configuration, and the outlet is an offset tip with a 3-inch outside diameter. This part cross-references AP Exhaust 30006 for the same application.

What It Helps Address

  • Rust or corrosion in the original muffler assembly
  • Exhaust noise caused by a worn or damaged muffler
  • Factory exhaust fitment issues after replacement
  • Leaks at the muffler connection point
  • Loss of OE-style exhaust routing on the left side

Installation Notes and Tips

Verify the vehicle year, model, and left-side application before installation. Confirm the inlet flange style, offset configuration, and outlet tip dimensions match the existing exhaust layout on the vehicle. Because this is a direct-fit muffler assembly, alignment with the factory exhaust path is important for proper sealing and fit.

Compatible With 2009-2014 Nissan Maxima, left; 2016-2017 Nissan Maxima, left; and 2018-2019 Nissan Maxima, left.
