New 570 strange noise/problem

I just bought a 2016 570 and love it so far. It currently has 13 hours on it. I took it for a road cruise this evening (about 7 miles, and going between 25-35 mph) and about 6 miles in I stop at a bridge to have a look at the water. When I stop, I feel the ATV shaking a little bit, and the exhaust note is slightly loude . Almost feels like I had an aftermarket exhaust o . I kill it, wait 5 minutes, then start it back up to it doing the same thing. I put it in N and start to rev it a little, but as soon as I do there’s a loud POP from the engine, and the noise/shake went awa . So I drive it home, and just as I pull into the yard and slow down, there’s a horrible growling noise/feeling coming from the ATV. Almost like something is getting hot or binding up. I loaded it on the truck, and it won’t be coming off until its at the deale . I always ride it easy (scouting crop fields), never had it in water deeper than 6", and no mud. It has stock sized Bear claws on it.

Anybody know what the hell went wrong????
