I would be a little leery of it myself. its a yamaha motor right? what yamaha sleds was that motor used in? may find aftermarket or cheap used pipe(s) somewhere.
its befor it had tuned pipes

It has to have some sort of pipe for back pressure and for scavenging. you can modify any pipe from the right cc motor for the proper effect. May not work perfect but will work.
