Ya i read the whole header forum and it was helpful. I have one simple to the point question. What is EVERYTHING(Including services, clamps, glues, anything down to everything wheather it's 50 cents to 50 bucks) that i will need to get Pacesetter headers right from the box to be perfectly sealed onto my 2000 GTP ? My local shop is doing the work so i want to supply him with everything he needs from the start without having to run back and forth.
