Got an 06 800 X and the guy who sold it to me finally got me the other can that he had. So pulled off the stock suit case that is on there but there is a ring on the inside of the top of the can that goes into the pipe. It would appear that I need to get that out to put on the other can but it is stuck in there. I know they are quite soft (looks like it may be aluminum). Any suggestions on how to get it out of there without damaging the can opening there or the ring? Thanks.
