These headers fit the 2003-2004 4Runner with the 4.7L V8 engine.

The headers are made from 14 gauge 304 grade stainless steel and come with a bright silver ceramic finish.  This is a shortie design and is intended to have the OEM catalytic converters welded to the collector of the headers.

Primary tube size is 1-5.8″  The flange is 3/8″ and ground flat to use the OEM style cylinder head gaskets.

These stainless steel shortie headers are a fantastic way to work some extra horsepower out of your 4Runner. Plus, they are a much more economical way to replace the crack-prone factory manifolds than heading to your local dealership. All American made, and backed by the Doug Thorley lifetime warranty.
