My brother and I have the GYTR Pipes on our Raptors. His spark arrestor fell out or melted or something this weekend. Does anyone know where to get another one or what the part number is? My local dealer can't find it. Also, if he chose to leave it out, should he re-jet? I know that Yamaha says not to rejet with this pipe but that is with the Spark Arrestor installed.

I've got a K&N jet kit, GYTR Pipe and Pro-Flow K&N filter. He, as far as we know, has the stock jets b/c he bought it used with the pipe already installed. Any help would be appreciated.
