exhaust on a six

[mark 68]

I've seen other discussions here and there, but what is the best sounding exhaust for a six. At this time I am running a 250 bored 30 over with a 230 head. It has stock exhaust manifold (and 1 barrel intake). Running to a 2" (guessitmate) pipe through a turbo muffler. Sounds pretty good now but curious about other mufflers. Like to have more of a deeper sound with out the rice rocket buzz. Future plans do include some clifford goodies.
