I have a set of bbk long tubes and x-pipe for my 97 cobra that I am now going to I think just part or sell that car. Hear is the question, are the headers the same as the 99-04 anyone know the difference. The part #'s don't seem to be the same in the summit I am looking at. But will they work for my dad's 99 cobra? I want to know before I pull his car a part and go threw the trouble of finding out they are not going to work. is it just that I have to lengthen some wires?
