The cat converter resides inside both exhausts, you will need intensive surgery, because the original cans are not serviceable, you need to cut them open at both ends and get to work on a dremmel saw to cut the catalytic unit from both cans, then weld them back together making sure they are straight?

Is it worth the trouble when you can get a set of Carbon Can Co for �260? When you resell the bike people might want the bike in original conditions and that type of surgery is irreversible, whereas you can sell your :CCC: here and make most of your money back.
