## Description

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 noticable 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. APPLICATION SPECIFICS: 2000-2004 Toyota Tacoma, 4-Runner / 2.4L-2.7L, stock manifold with dual outlet flange and rear facing EGR tube, 2/4WD. (see THY-511-C if your stock manifold has a single outlet flange and no rear facing EGR tube).

    header time.

Perfect fit, they look good, slight bit deeper tone than factory.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Strong and good looking manifold
  

*by 4***S on Reviewed in the United States on April 10, 2019*

Looks awesome, won't crack like the cat iron stock version.But, not quite identical dimensions/angle, so I now have an exhaust leak until I can get the pipe bent to mate to the manifold outlet.
