They look like the Dan Moto Conical GP exhausts
Honda CBR 1100 XX Blackbird 1997 - 2007 Conical GP [EX-00196] - $248.40 : Danmoto, Motorcycle Racing Parts & Accessories
I had Dan Moto carbon fiber slip-ons on my 03 XX. Not too loud putting thru the neighborhood. Are not as loud as they look like they would be when you wind it up. AND very reasonably priced and look very cool. I would've put them on my 2016 ZX14R, had they been available, so I went with Delkevic CF ovals.
