Product Details

Walker Quiet-Flow SS 47774 is an exhaust muffler assembly engineered as a direct-fit OE-style replacement for the Toyota Tundra. The Quiet-Flow SS product line focuses on stainless-steel construction and factory-style fitment, making it a practical choice when replacing a worn or noisy muffler on 2000-2006 Toyota Tundra models. The oval body measures 21 inches in body length, with a 9-inch body diameter, 9-inch body width, and 7-inch body height, while the overall length is 81.625 inches. This configuration supports a stock-like exhaust repair without changing the vehicle’s original routing more than necessary.

This part cross-references AP Exhaust 54968 and BRExhaust 285-825 for the same application.

Common Problems It Can Address

• Exhaust noise from a rusted or damaged muffler
• Corrosion-related muffler failure on Toyota Tundra exhaust systems
• Factory exhaust fitment issues after replacing a worn muffler
• Restricted exhaust flow caused by internal muffler deterioration
• Need for a direct-fit replacement on 2000-2006 Toyota Tundra models

Installation Notes and Tips

Verify the inlet and outlet configuration before installation: this assembly uses a 3-inch spherical flare inlet and a 2.5-inch pipe connection outlet with offset routing. Confirm the vehicle’s emission system when ordering, since fitment includes standard, Federal Emission System, and California Emission System Toyota Tundra applications. Compare the original muffler dimensions and exhaust path to the replacement part to ensure proper alignment.
