Tire rubbing exhaust on bumps?

[Tiddys]

Hey y’all 2020 TT250 with the eBay CRF230 exhaust everybody gets for them. Put new shinko tires on today after 1500 miles (low for 2 years I know) and noticed that gahhhhh damn my exhaust been getting torn up! I did ride her pretty rough in the mountains and put that rear shock to full use. I’m guessing this would be the tire rubbing and not like rocks and sand getting shot out at it? I don’t feel the tire hitting anything but I sure feel that shock getting compressed.

Anyone else have any issues with this?? How would you fix it?
