those are Borla!!! i had them on my 96 900ss/cr, they were great, i actually had them set up as a double stack on the right side, very cool! they did indeed come with a carbon fiber strap/hanger from the factory. i just sent my cannisters off to Doug at ARC Fabrication and he's making them into a full undertail system with a spaghetti header...he does AWESOME work!!!!!!!!
