Those are cartoon like. Yuck! Head pipe section looks ok tho. I wouldn't be beyond chopping the ugly flare off the pipe and ripping any muffler packing or baffle out and giving it a try. You never know what might make a pleasant noise. In my experience most xs mufflers sound bad, weak, or too quiet. Best sounding outside of straight pipes I ever ran were the short baffled turn outs. Weren't loud enough for trouble in most places but still sounded like a bike!
