Are you sure there is no baffles in there and not just lightly baffled? The set of TOR that I have are the first generation, the later generation ones have been baffled alot less each time. I think I remember that the latest ones are more free flowing, straight through design(you can pass a golf ball through them).
If in fact you don't have baffles in there you should be able to install a set of aftermarket ones in there.
