Product Details

Walker Quiet-Flow SS is the brand’s stainless-steel muffler line for drivers who need a replacement assembly with factory-style fit and durable materials. This product line focuses on broad-market stainless-steel construction and OE-style replacement geometry, making it a practical choice for exhaust service on domestic and foreign vehicles.

The assembly features a 9-inch body diameter, 7-inch body height, 18-inch body length, and 9-inch body width, with an oval shape and natural finish.

This configuration supports replacement of the factory muffler assembly on the listed Sentra applications.

This part cross-references Monroe Shocks & Struts (e.g., 145-785) for the same application.

What It Helps Address

Installation Notes and Tips

Verify the vehicle’s emission system and exhaust configuration before installation. This muffler assembly is listed for 2013-2017 Nissan Sentra models with Federal Emission System or California Emission System, and for 2018-2019 Nissan Sentra applications. Confirm the 2-bolt welded flange inlet, offset inlet and outlet layout, and 3-inch outlet tip match the original exhaust setup before beginning service.

For best results, compare the existing muffler dimensions and connection style to the listed specifications: 42-inch overall length, oval body, and stainless-steel construction. Proper alignment of the exhaust hangers and flange connection is important for a secure replacement on Nissan Sentra exhaust systems.
