You have a lot to learn about cars, my friend. Perhaps you should look into blacksmithing instead.
You don't "break in" any muffler. Sometimes the tone changes over time, but that is because the muffler is
breaking down, not breaking in. If you intentionally destroy the packing, which functions as sound deadening material by damping sound waves as they travel through it, you are basically eliminating what little sound damping capability the muffler had. Don't do it.
Glasspacks are not high performance mufflers. They are often more effective as resonators (used to change the tone) than as mufflers (used to lower the volume). If you use a glasspack as a primary muffler, it will usually sound absolutely terrible on anything but a very old, very low compression, very low-revving engine...I'm talking about pre-war stuff here. If you have a '41 Ford with a 59AB flathead running about 8:1 compression, a pair of Cherry Bomb glasspacks is just what you need. It will sound like a grizzly bear gargling honey. If that's not what you drive, keep shopping.
I know that there are still old guys in corner muffler shops and pimply-faced kids working at AutoZone who will tell you that a glasspack is a great high performance muffler because you can see right through it. Believe me, they are wrong. Most of them don't know doodoo from apple butter about engineering. That's why they work at corner muffler shops and AutoZone. Do not seek technical advice from the D students of the automotive world.
