knackered exhaust.

I am going to "stubby" my exhaust. I have never done this before so want a practise can to do it on first.

Is there anyone out there that has a can that is not really worth selling but would be happy to let me have it and practise on?

My aim is to drill out the rivets at the outlet end, cut the can down and rivet the outlet back on again.

Cheers.
