I have a Two Brothers exhaust can with a hole in it. It’s really more than a hole, it’s like a big gash in the side. The inlet and outlet pieces are in perfect condition but my bikes PO somehow managed to have this happen. I don’t want to just chuck the thing so I’m wondering two things: 1) could I fashion a patch? 2) could I fabricate a new can and put the inlet and outlet in the new tube? What grade of aluminum sheet would be the easiest to work with? Edit: a bit of Google-fu indicates that 3003 or 5052 would do the trick. 6061-T6 is not recommended. I’ve taken it apart and it’s nothing more than an aluminum tube with a baffle and packing inside. So low tech it’s almost laughable.
