    Exhuast Question

    Alright, long story short-I got a 1979 GS850 for free...yes free. (I went to a garage sale and the guy said I could just take it, so needless to say, I did). It is currently in the process of becoming a running bike again (after new rings and gaskets), and now needs a new exhaust. My question is this-is there a way to get a newer style sportbike exhaust on this great old bike? I am sort of giving the bike a style update-starting with the exhaust. The look I am going for can be seen here-
    www.redneckcycles.co.uk-then click on street fighters on the left, then on the GS850. Looking at the pictures they have, it seems the only way is to get a header built for the bike and weld on a newer style muffler section. Any help would be appreciated-thanks.

      I don't know the answer, but I like what you're aiming for!

        Well, I thought maybe I could get a nice header that was built for the bike, the grab one of the half exhaust systems from Yoshimura or something and weld it on...

          Thats the same thing I was thinking when I bought my MAC exhaust.
          Sadly, the Mac header is 2.5 inches where it would connect to any mid-pipe or muffler can.

          The only choice is to have a mid-pipe MADE that will fit the huge mac header outlet and the smaller modern muffler inlet.

          Fkn sucks...

            This is my bike when I got it last fall:


            That's a V&H header with a modern D&D pipe. The midpipe is a single bend, looks real simple. I think the V&H header has a 2" output, so it would be easy to configure with a modern slip-on can.

            Also, I think the V&H exhaust exactly like that 850 has is available. One of the New England GS guys, Pano, just put a nice modern V&H on.

              Just as a side note-nobody has ever seen another seat like the one in the first pic from Redneck Cycles have they? I'm trying to figure a way to create something like it, but it would be nice if something similar is already available.

                Okay, seems like that is a good answer-just get a header with a two inch or so output to fit the bik, fab up a midpipe and bolt on a newer can. Any other thoughts are welcome.

                  That's exactly whats going to have to be done. (Vance and Hines Header)
                  OR
                  Get a mid-pipe "expanded" to fit over the 2.5 inch MAC header.
                  (I may take this route if I can get a good deal on a can and mid-pipe together)

                  Oh yeah, that seat and rear subframe are one-off pieces made
                  by the former Redneck cycles of the UK.

                    That's what I figured about the seat, oh well....it sure does look good though.

                      I didn't bend or stretch anything to get this R1 to fit the headers I have. Don't know what brand they are, doesn't mater. AutoZone has adapters to make anypipe, midpipe marry your header. Two reducers, less that $4.00, instant exhaust system.

                        Thanks for the info--just another side note....is there a way to change the bodywork/tank on my 79 so it is a little more modern and sporty like the ones pictured above?
