07 Sprotsman x 2

Does anyone know where to find a used muffler for a 2007 800 sportsman x2. A previous owner replace it with a Aaen aftermarket. It is a little noisy for me I like the mostly quite ride while in the woods. If any one knows where I can get one or if someone would like to trade for it Im all in. I can get a new one but I guess since its an x2 they want a lot more for it. Thanks
