I'm not going to vote because I all ready have a set of gp pipes on my 18. I origanially wanted side by side but where not avalibale. I have grown to like them even thought the left side of the bike looks like it's missing something. I think you should make a batch of left pipes that would fit with the gp style right to give the stagered look of the 88 mc18. You could make a bunch of right sides and then mix up how the lefts are made and make every one happy . Them for people like me I could just change the left pipe to fit my mood.
