I think I have a decent one around here. I think it's been bead blasted and I do need to verify that it's the correct size (I show the FZ750 but I think it's the same). I do have another Kerker that we just got back from bead blasting which is decent and from a Vmax but I wasn't thinking I wanted to sell just the muffler but might do that since we have done custom mufflers before to take the standard one off.
I can of course provide new but they aren't terribly cheap (even with our Kerker pricing).
