Glasspack?

I am just wondering if its possible to put a little fiberglass into my sweet thunder side pipe baffles to quiet them just a little?

how would you prevent the fiberglass from blowing out? Which size are you running? Try a smaller size.

There are baffles but after looking more closely at the inserts, not sure how I would stuff fiberglass in them. Maybe just at the front of the inserts?

It would blow right out.

You could get the Hooker glass pack inserts.

I have the 2 1/2 inch sweet thunder inserts, which were loud , so I drilled lots of holes all the way through both steel layers and wrapped some muffler steel wool over the holes and then wrapped some muffler figreglass wrap over that and used some wire to tighten it down. They didn't leak or blow out.It did reduce the noise considerably.
