C.A.R.B. Number: EO# D-540-6
Doug Thorley Headers THY-511Y-1-C tri-y headers deliver the ultimate in performance and gas mileage for your 2000-2004 Toyota Tacoma, 4-Runner. Doug Thorley Headers is the originator of the tri-y header design, which is the most efficient way to increase horsepower and torque over a broad RPM range, and more importantly the range where you use it most. That better exhaust flow produces noticeable gains in horsepower and torque output, while increasing fuel efficiency.
The headers are manufactured using heavy duty 14GA steel tubing, and super flat 3/8 inch head flanges. They are then silver ceramic coated inside and out, which looks great, drastically reduces under-hood temperatures, and creates a strong barrier to protect the headers from the environment.
