you will need to shorten the core the same amount that you remove from the end of the can (as you cannot reuse the previous rivet holes). Shorten the end of the can , just enough to remove the bad holes. if at all possible use new holes in the end cap as well as on the can and here is the important part DO NOT USE ALUMINUM RIVETS!! you need steel, stainless steel are the best (they are hard on your rivet gun ) they will hold up to the heat, the aluminum rivets will not. put a little high temp sealant on each rivet as you go. the thre keys are steel wool (not soap pads!!) new holes and stainless steel rivets). you will have to have other holes welded up.....in this case you may be better off getting another can off ebay, but the maintenance should be as stated above. good luck.

The aluminum housing will wear out over time with the heating and cooling of it from riding???
Not really sure why this is hard for you to understand.
As soon as the first sign of wear to one of the rivets occurs, it's all down hill from there, unless, you stop riding, fix all the rivets, re-pack the silencer correctly, and move on.
If you just keep riding on a bad part, it's not going to get better!
You have destroyed the can, and all the parts now.
