Need Advice on Exhaust

Just prior to my days of hot rodding people would put on "Smitty"s. A straight through steel pack muffler. By the time I was actually working on cars the standard for exhaust volume became the "Thrush" and then the "Cherry Bomb" glass pack. We had an oil boom in the area and the folks coming up from the south used "Blue Boys" instead of "Thrush" or "Cherry Bomb". I found out they were a generic blue glasspack. I got some back in the day from Warshawski & Co. (later J.C. Whitney).
