    Aftermarket exhaust won't fit...

    So I bought a MAC exhaust from a GSR member, the headers line up and go into place. The issue I'm having is that the exhaust flanges won't go up against the motor, by about a half inch! I wish I had pictures but the pipe ends seem too long for the exhaust ports. Why is this? Am I supposed to use new bolts and let the flanges bolt on from that distance?

      You could use longer bolts and pick up some kind of spacers from Home Depot or that type store. Maybe not ideal but probably okay.

          contact the GSR member you bought it from and ask him how he managed to fit it. you may be making a silly mistake or he may have taken you for a ride by selling you the wrong pipe

              I think this is normal for aftermarket pipes. Here is a pic of what my Vance & Hines looks like on the GS. My last Honda had bassani pipes that were the same way. You probably just need longer bolts that would normally come with the exhaust but since it's used they may not have been included.

                  Just a thought, did you put new exhaust gaskets in without removing the old ones?

                      Okay, this is what it about looks like. I trust the member I bought it from, no way he took me for a ride. Thanks a lot Arkmage, this really helps! (I'm under pressure to move it out by tomorrow by my boss while I'm renovating my basement, yadayadayada)
