I have an (new to me) 2008 Teryx that has had some mods done to it along its journey in life. At some point it got an open style air box and a set of dual Dragonfire pipes, so I assume it is jetted, etc. All these things are good except... I am going deaf! Is there a better option for these old machines? It is so old I am assuming my choices will be limited. I am hoping for some real life experiences to help me make an informed choice.
