i agree, the size of the baffle makes the difference, smaller diameter will make it raspier, larger, deeper. thrush glasspacks neck down, say you get a 2.25" inlet/outlet, the through tube will most likely be 2", and its a perforated baffle, no louvers, i like this about the thrush, what i didnt like was the necking down
