OK I have now got 2 aftermarket cans that don't fit. What is the difference in the pipe on the different year tripples. Mine has a steel ring on the end of it, the bender can I have looks like it needs one with a gasket like on the 500 to make it fit. Can I just replace the fat pipe with one from a newer sled, or what can I do to make it work. I'm tired of buying cans, so this one is going to be made to work. Thanks Maxdlx
