Product Details

Walker EPA 14662 is engineered for the right-side exhaust position on the Toyota 4Runner and Lexus GX470 listed above. The direct-fit layout follows the original manifold-style exhaust path, while the ECO III catalyst design supports emissions-system replacement needs on 1996-and-newer OBDII vehicles. If you are sourcing a Walker catalytic converter for a 2003-2004 Toyota 4Runner right side or a 2003-2004 Lexus GX470 right side, this part number provides a focused fitment match.

The Walker EPA product line is positioned for Federal / EPA applications and emphasizes emissions compliance with a direct-fit format. Part number 14662 is also a useful reference when comparing Walker EPA 14662 against other exhaust manifold converter listings for the same vehicle coverage.

What It Helps Address

  • Failed catalytic converter efficiency codes
  • Exhaust leaks at the manifold-to-pipe connection
  • Check engine light concerns related to emissions performance
  • Restricted exhaust flow from a worn converter assembly
  • Replacement needs for a damaged integrated manifold unit

Installation Notes

Verify right-side fitment before ordering. This unit uses an 8-bolt welded inlet, a 2-bolt welded outlet, and one O2 sensor port, so the existing exhaust and sensor layout should be matched before installation. Confirm gasket and flange condition during removal, and inspect the mounting surfaces for warpage or corrosion before installing the replacement.

Quality Assurance

Walker designs this EPA direct-fit catalytic manifold to meet Federal emissions requirements for the listed applications. The premium construction and direct-fit format are intended to support a proper replacement on the specified Toyota 4Runner and Lexus GX470 vehicles.
