I am having an issue with exhaust fitment. On the left side of the bike I am having a problem moving the exhaust inboard enough so the gear shift doesn't hit against it when going into first. The muffler also barely clears the left shock as well. When installing the headers do they have to be seated in as far as they go or can you leave them out a little and tighten in place. Seems like a simple task but it's been a struggle for some reason.
