Okay, so I just picked up a K5 and I'm looking to install a Yoshi pipe. Before I install it on the bike I would like to shorten it 5"-6". Has anyone had any experience with this that they would like to share (what to do and not to do). Just looking at the pipe from the outside it apprears that one must drill the rivets out of one end (which end I don't know matters) and cut the pipe, drill new holes, and apply rivets. Do need to take any of the baffels out before I cut?? Repacking?? Any help would be great. Thanks!!
