Help im in search of a Acerbis Carbon Fiber Silencer

Ive been in search of a Acerbis carbon fiber silencer for the Cr 250 project im planing on starting. I havn't scene or heard anything about the silencers for a few years now. My father had purchased 2 brand new ones off of ebay. Im at a loss and was wondering if anyone had an idea of where I could get my greedy paws on one...

Thanks for your time
