3:1 Long Tube Headers, Silver Ceramic Coated

The Doug Thorley THY-515-LS-C headers are engineered to significantly improve the performance of the 4.0L V6 Toyota engine, as noted to "really wake up the motor." These are 3:1 long-tube headers designed with a focus on quality and performance. Constructed from premium T304 stainless steel, the headers are finished with a silver ceramic coating, applied both inside and out, which contributes to their durability and performance potential. The primary tubes measure 1-5/8" in diameter with 14-gauge thickness, connecting to a 2-1/4" collector designed for factory flange connection. The flange thickness is 3/8". This kit includes necessary hardware but requires the reuse of factory gaskets. It is explicitly stated that these headers are NOT LEGAL FOR STREET USE ON POLLUTION CONTROLLED VEHICLES and CANNOT BE SHIPPED TO THE STATE OF CALIFORNIA due to emissions regulations (CARB E.O. #: Not specified as legal). The product comes with a Limited Lifetime Warranty to the original purchaser. These headers are compatible with a range of Toyota models equipped with the 4.0L V6 engine, including the 2005-2011 Toyota Tacoma, 2007-2012 Toyota FJ Cruiser, and 2003-2012 Toyota 4Runner, Hilux, and Land Cruiser Prado. The product notes state that the engine is the 1GR-FE with dual VVTi cylinder heads.
