when i bought my 95 rs, it came with some headers in the back and dude that sold it too me said that all it needed was a flange welded onto it. I have the motor completely out of my car now and i have compared the headers to the stock manifold. The headers are longer and if a flange is welded on then it wont line up correctly with the down pipe. From the small amount of research i have done i think i have a cup ball joint or something like that, i just dont see how to connect it to the down pipe, any suggestion?
