ATV Performance Modifications Will XP exhaust fit on Sportsman 500? May 27, 2015 Theres a guy near me selling a Looney Tuned exhaust for an 850 XP for a pretty decent price. Question is, Is there any possible way that I can make it fit? I really wish I hadn’t sold my Big Gun exhaust, but man was it really loud for me.
