fiberglass muffler
can someone clear this up for me? i thought fiberglass packed mufflers would burn out quick on a TII, that a steel wool packed (or something like that) shoulod be used for longer lasting... so i guess Dynomax and some other mufflers would burn out sooner since they're fiberglass packed?
or is it something else (a presilencer?) that will burn out faster? i'm in search a a muffler replacement and this is getting me confused...

Fiberglass won't last as long versus steel wool or even "ceramic wool".
For mufflers, fiberglass might last long enough (couple years) as the heat is not too bad up front.  Forget trying to use a fiberglass muffler for a pre-silencer - it will only last a month.

For rear mufflers, they're fine. But if you plan to use them in front in place of the cats, they won't last more than a few hours (as Ted said).
My fiberglass packed rear mufflers have been fine for 3 years, but I still run a cat. We will find out what really happens in the spring when I go full 3" and eliminate the cat and resonator.

That should be REAR, not FRONT - or it gets confusing.

what brands of mufflers utilize the steel/ ceramic wool for packing? most mufflers you guys have are fiberglass from what i'm seeing (ie. dynomax and the rest...)
