blew out a muffler today

[stroker402]

i have dynomax ultra flos on my 65 barracuda 273 , today after jumping on her alittle must have I blown the fiberglass matting out inside the muffler or something, because it got a lot louder on one muffler. it's welded casing and nothing is loose rattling..... never had that happen before.... anyone else run into this situation?

Yep. Glasspack mufflers can blow out the glass packing.
I had a pair of glasspacks so blown out that if you hit them with a wrench, they would ring like a bell. About 95% of uncorked.
They got real old, real fast.
