Product Details

Walker 47815 is built as a direct-fit exhaust muffler assembly for vehicles that need an OE-style replacement rather than a universal muffler. The Quiet-Flow SS product line combines stainless-steel construction with application-specific fitment, making it a practical choice for restoring exhaust function on a 2004-2013 Toyota Highlander, 2007-2009 Lexus RX350, and 2004-2006 Lexus RX330. This part cross-references AP Exhaust 7047 and BRExhaust 286-299 for the same application.

What This Muffler Helps Address

  • Exhaust noise from a worn or damaged muffler
  • Rust-related failure in the muffler body or internal structure
  • Factory exhaust fitment issues after prior repair work
  • Leaks at the inlet or flange connection points
  • Loss of proper exhaust routing on Toyota Highlander and Lexus RX models

Installation Notes

Fits 2004-2013 Toyota Highlander, N/A. Fits 2007-2009 Lexus RX350, N/A. Fits 2004-2006 Lexus RX330, N/A.

Verify inlet and outlet orientation before installation: offset inlet, center outlet, pipe connection inlet, and 2-bolt welded flange outlet.

Quality Assurance

Walker Quiet-Flow SS muffler assemblies are engineered as direct-fit OE-style replacements and use stainless-steel construction for improved durability versus typical aluminized mufflers. Part Number 47815 is part of Walker’s Quiet-Flow SS line for domestic and foreign vehicle applications.
