Description

The Doug Thorley THY-564Y-LS-C headers are engineered as a performance upgrade for the 2003-2004 Toyota 4Runner and Lexus GX470 equipped with the 4.7L engine. These long-tube, 4:2:1 Tri-Y headers are constructed from steel and finished with a silver ceramic coating for durability and heat resistance. They include 02 extensions to facilitate proper sensor integration. Designed for LS engine swaps (4.8L-6.2L), these headers are compatible with both 2WD and 4WD configurations of the specified vehicles, provided they have a coil spring front suspension. It is important to note that these headers will not fit Heavy Duty, Big 10 Chassis, or Heavy Half truck models. For manual transmission applications, a cable or hydraulic clutch linkage is required. These headers are manufactured in the USA. Please be aware that this product cannot be shipped to the state of California.
