Going to install LT headers soon
With that being said, i've installed QTP headers on a few cars, very easy stuff, just time consuming. Take your time and make sure your car is safely lifted in the air before you get under it.
What I like to do for added safety is drive the rear wheels up on rhino ramps, then jack the front of the car high enough to slide another set of rhino ramps, therefore your vehicle is laying on 4 rhino ramps, so when your installing the headers and the car is really high and if by any chance the jack gives out, the car will come down on the rhino ramps and possibly save your life. Not likely to happen, but you never know
