Walker 21213 Exhaust Muffler - Right

Walker Quiet-Flow SS Muffler

The Walker Quiet-Flow SS muffler, part number 21213, is a specific-fit exhaust replacement built for controlled sound and steady exhaust flow. It fits 2013-2018 Toyota Avalon, right, and uses stainless-steel construction for corrosion resistance in demanding exhaust environments.

Key Features

• 100% stainless-steel body for long-term exhaust durability.
• Precision-fit design for a direct replacement application.
• OE-style sound characteristics for a factory-like exhaust note.
• Oval muffler body with offset inlet and offset outlet layout.
• 2-bolt welded flange inlet and tailpipe outlet connection.
• Hanger included for installation convenience.

Detailed Description

Walker Quiet-Flow SS 21213 is engineered as a premium exhaust muffler for drivers who want a specific-fit replacement with stainless-steel construction and a refined sound profile. The oval body measures 16.000 inches long, 11.000 inches wide, and 5.500 inches high, with an overall length of 31.350 inches. Inlet and outlet sizing, offset routing, and welded flange connection points support a clean fit on the listed Toyota Avalon application. This part cross-references Monroe Shocks & Struts (e.g., 174300P230) for the same application.

What It Helps Address

• Exhaust noise that has become louder or uneven.
• Rust-related muffler deterioration in the exhaust system.
• Fitment issues from a worn or damaged replacement muffler.
• Loss of factory-style exhaust tone after service.

Installation Notes and Tips

Confirm inlet and outlet orientation, flange style, and overall length before installation. This muffler is not reversible and is not tunable, so the listed routing must match the vehicle application. Verify hanger placement and exhaust alignment during installation on the Toyota Avalon.

Quality Assurance

Walker Quiet-Flow SS mufflers are part of a product line focused on stainless-steel construction, precision fit, and OE-style sound. Part number 21213 is built for the specified application and follows the Quiet-Flow SS design approach.
