I have recently got a 02 polaris trail boss 325 and want to know what performance mods that I can do I have already found a jet kit but thats about it. I would really love to put a universal type muffler on mainly for a better sound (i build cars for a living so sound is very important to me).Im not looking to race it or anything like that just have fun with it and build a little more power. Any help would be much appreciated.
