The thing that is stupid to me is the Hookers aren't that much harder. As far as I understand it the only difference is dropping the linkage/maybe pulling the column. With TTI's/Dougs, you still have to jack the car up 3 feet. Jack the engine up. Pull the starter. And ram jam them in there. I mean I had to jack the engine up just to get the manifolds out. So it's really not that much more work for the Hookers. The dougs/ttis just fit nicer. The only thing I dislike on the Hookers is spark plug access on cylinder 7.
