If going original, and as Bryan says original genuine Honda ones are very rare in good condition, then see if you can find genuine hanger brackets, DS sells copies but they are not bent in the right shape and it causes misalignments when fitting the exhausts. You can find the brackets on Ebay, you may pay a little more but they are better.
I have a set of the copy exhausts waiting to be fitted, TBH I think they are better than the originals, mainly because the originals weren't chromed on the back, just on the outside that you see, they were just dull silver and they started to rust through that far quicker than the chrome side.
DS used to sell the exhausts separately, which could have been handy as I have 2 original exhausts in nice condition which I may sell soon. Both left hand side ones, No1 and No2 cylinders.
