3:1 Long Tube Headers Silver Ceramic Coated T304 Stainless

The Doug Thorley Headers THY-515-LS-C is a set of 3:1 long-tube headers engineered to significantly boost the performance of the 4.0L V6 Toyota engine. The headers feature 1-5/8" diameter primary tubes constructed from robust 14-gauge steel and are designed for a factory flange connection at the 2-1/4" collector. This kit is noted for its ability to "wake up" the 4.0L Toyota motor, providing noticeable gains in power and responsiveness throughout the entire RPM range. The package includes all necessary mounting hardware, though users will need to reuse their factory gaskets. The design emphasizes quality and performance, aiming to be the ultimate header upgrade for compatible Toyota vehicles. Important fitment and legal considerations apply. These headers are designed for the 2005-2011 Toyota Tacoma, 2007-2012 Toyota FJ Cruiser, and 2003-2012 Toyota 4Runner, Hilux, and Land Cruiser Prado models equipped with the 4.0L V6 engine. Crucially, this product CANNOT be shipped to the State of California and is NOT LEGAL FOR STREET USE on pollution-controlled vehicles due to California Air Resource Board (CARB) regulations.
