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.
 
That frozen concoction that helps me hang on….
 
I knew a feller who had one of them there Knock off Jine-ease carburetors. Apparently it was dumping fuel and loaded up the cylinders so bad that when he finally got it to fire it blew his passenger side muffler to Kingdom come...I looked under the car and the muffler was wide open like the gash in the Titanic...I looked at him and said "what the hell happened here? did ya have a muffler explosion?"
 
Some people say that there's a woman to blame.
 
Damn, you all crack me up.LOL! You just click together.

As to mufflers, anything with fiberglass I ever ran I burned out. We seem to live
now with a bunch of high $$$-junk. Here in New Mexico we have a large car and
truck hotrod culture. Every time my wife and I head into town we seem to comment
on the weird sounding exaust. Not how loud, just "was that a weed whip? sound
affect from a cheep syfi movie? 1 out of 40-50 sound old school bad a**. In the
70s-80s headers, long glass pack (Thrush-Cherry Bomb- Smitty's-Purple Hornies ect.)
with short pipeing sounded good but would burn the packing out in a few months
like stroker402 mentioned.
Full length to bumper glass pack would rapp and sound weird, so to get
away from that you went to a "Turbo 2 baffle style, Thrush-Cherry Bomb again"
Sounded great, until the outer skin would flutter at idle, remember that?

Back then a muffler quieted the sound without loosing the open header profile.
Now it seems the aim is to not' sound like a well tuned engine? What happened,
I'm OLD :wtf:
But damn, I love the sound of a well tuned engine, loud or quiet.

Stroker402, glass packs never lasted long for me just like yours.
Try Porter steel packs, I think they are still around. I think Porter is
the right name, they lasted longer than glass packed with slightly
different sound but still like a glass pack.
