I have a 2019 Polaris 1000 xp with 17hrs on it, at about 14hrs I started hearing a rattle that seems to be coming from somewhere on the exhaust but I can’t tell exactly. I’ve tightened all the bolts on the heat shield and tried hose clamps on the shield behind the muffler with no luck. I can take it in for warranty but would rather fix it myself then have to leave it with them for who know how long. Any ideas??
