These long tube headers from Doug Thorley fit the 2005-2009 Toyota 4Runner and Lexus GX470 with the 4.7L V8 engine.

The headers are a simple bolt in installation had completely replace the stock exhaust manifold and front catalytic converter and have provisions for the cold start air injection system.  The headers run from the cylinder head and bolts to the Y pipe.  URD also offers performance Y pipes as well.

Made from 304 grade stainless steel and ceramic coated in a bright silver color.  Ships with all needed hardware including gaskets and includes extension harnesses for the front O2 sensors.

Removing the front catalytic converters with these headers will set a check engine light.  URD offers our UNIVERSAL Rear O2 simulator to help prevent the check engine light.  We offer it bundled with the headers at a discount.  You can find more information on the UNIVERSAL Simulator here.
