I have a used carbon fiber oval shaped Micron slip on exhaust for Honda CBR929RR and CBR954RR. Comes with mounting bracket which goes directly to your rear foot peg. The muffler is in great condition with no major scratches or dings. Has a great deep sound at idle and then as RPM's increase above 5000RPM it gets pretty loud! It is a direct replacement for your factory muffler with no additional hardware needed. Please let me know if anyone is interested, I'm selling it for $275 shipped. Here's a picture of it:

It is now on ebay if you are interested but didn't say anything:
