are glasspacks that much worse than bullets? I have a couple of summit "glasspacks" that sure look like bullet mufflers.
I'm not sure what the real difference is, but their exterior design is the same, so it seems. what's the big difference in them?

Yeah the louvers are the difference between a glasspack and a bullet. Bullets are perforated inside, so there's little to no turbulence as the gases pass thru. Glasspacks have the louvers that "catch" the exhaust, routing it thru the fiberglass packing, steel wool, whatever they use as packing. Picture a chambered muffler before it gets "chambered"... that's a glasspack.
An ol'-skool trick is to get glasspacks REAL dag-gum hot with a torch, and soak them with cold water. That busts the fiberglass into pieces small enough to pass through the muffler and out the pipes with a few good WOT revs. They say it frees the flow a bit and makes them sound meaner.
