Best glasspack to run?

Back in the old days, when I was young, I swapped gears and exhaust systems on my 57 Chevy on a monthly, if not weekly basis. I usually put the quiet (sort of) turbo mufflers on with the 3.08s
When the 4.56s were in, I usually had some glasspacks that were basically header mufflers..... only there was NO glass left. Hit them with a wrench, they would ring like a bell.
I'm sure I was very popular with the neighbors.......
