    Doug thorley headers

    I have a set of brand new headers that never got installed on my 5.9. They are still in the original box...... Here is the listing details taken from Amazon but I don't think they fit 1999 like they sy they do. 700.00 shipped or best offer. Mike




    Doug Thorley Headers THY-630Y-C long tube tri-y headers deliver the ultimate in performance and gas mileage for your 1993-1999 Jeep Grand Cherokee. 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: 1993-1999 Jeep Grand Cherokee, 5.2L-5.9L V8, with EGR, 2/4WD.
