David, I figured out the mounting adapter it seems to work pretty well. As far as the exhaust I shortend the baffle by about 2" and as shortend the pipe where it goes into the baffle by another 1". I thought about bending the center stand or the pedal and as you say that maybe my only option.
For now I'm going to upjet and make sure I get the performance boost I'm looking for before I worry much more about the pedals hitting the exhaust.
I'm still bummed that this didn't just mount up with no modifications. I did tons of research about this before buying and this seemed to be the way to go. Maybe the one I got was just welded wrong? Or maybe the center stand on my 103 isn't the original stock. All I know is this has been a major pain in the ass.
