    stock HO headers bolt right in?

    Im wondering if i put a set of stock HO headers on my merc if they will bolt on to my original exhust without much or any modification??

    depends what you consider not much. Can you weld.? Would you consider welding 2-1/4" collectors to your stock converters a big project or a little project.?
    In other words. Mustang pipes are 2-1/4", stock lo-po's are 2".

        Might need new bolts for attaching them to the head, not sure.

            If you're replacing the H pipe, its easy. Yes, need different bolts but thats it. Actually the short bolts from the manifold are the correct ones, but might as well install all new. I would also suggest using lock washers. No need for special header bolts either, there is plenty of room around the stock headers for a regular socket on a normal size bolt.

              My stock HO headers were 2-1/2", they are removed now, so they are available for purchase if wanted.

                yea, the headers will bolt right in very easily, but as for the rest of the exhaust, I'm not sure...
                When I took off my old manifolds, the rest of the exhaust just fell off...LOL
                so I took it to a shop and had all new piping installed.
