What's the difference between a glasspack and a resonator?

Glass pack is an archaic term for a straight-through resonator. They were louvered-core, which is bad. They also used fiberglass packing, hence the name. Any resonator you get, no matter what the moron at the shop calls it, should be a perforated core and use stainless steel packing.
