I, too, blew out my carbon can on a ride.
Fixed it with a wrap of tin and some pipe straps. Is still holding after a few thousand miles of hard riding.
Wish you much luck finding a replacement.
"Big Bertha" my KTM 950 SliderMoto with 19/17 spokes, FCR41's, 2-into-1 high pipe, single side front brake and handcut flattrack style tires. Gettin Slideways is good!
