The BAFFLE fell off of Honda CRF 230 - replaceable? New exhaust?

I would say no. Is it just a slip on? Or was it clamped,? welded? How did it fall off? Even if the guts came flying out the end, they can be put back in. My exhaust system is just pressed together, I can pull it apart and rewrap the fiberglass and won't hurt a thing. Some exhausts are held together by a spring. Check it out. Hope this helps.
