Loud Exhaust/Rev Limiter

Went out ice fishing over the weekend. Everything was fine, the beast was ripping through the trails and flying across the ice, great riding Thursday & Friday. Then late friday I noticed my exhaust was starting to get louder. Now I only had 250 miles on her, so I figured maybe she was just starting to break in. Still had all of power it was just starting to get loud as hell, by the end of the day I had a screaming headache. Exhaust was hot all day but never cherry red or melting plastic. Just steaming from the snow.

Started it up Saturday morning to head out onto the ice and noticed the gauge pod wasn’t showing the gears (H,L,N,R,P) just blank(–). But fired it up anyways and still loud as hell. Warmed up and went out, but now I reached the rev limited quick. I mean I hit it doing like 30MPH at anything over half throttle, if I was lucky. Which obviously that isn’t right.

What did I do to her??
The exhaust I was thinking is the gasket, but then starting up the next day… Clueless. No error codes present.

Its still under warranty, I purchased it in Sept. So going to call the dealership here shortly, Its already in the back of my truck ready for drop off. 300 miles on her now and this already…

Just wondering if anyone has any insight on a issue like this. I’ve been reading the forums for awhile now and seen exhaust issues, but nothing on this. Wondering what I’m in for…
