The main differences between the different year models of K-bike exhaust are the way the muffler mounts to the back end of the left footpeg bracket. It is possible to fabricate a mount that will work with just about any muffler hanger. I did this several years ago and it worked ok.
Remus makes a system that will fit the different year models. I have had one for several years now with their quietest muffler and it is acceptable. I would rather have the quiet of the stocker, but finally gave up with the cracking.
I ended up with the muffler hanger from the K100/K1100 (16 valve models) that uses the rear two mount bolts of the footpeg bracket. It is stout and rubber donut equipped. Get the pipe that will fit those bikes and you are in business.
