Well, yes, you want to neck down far before the throttle body. You want a smaller pipe connected to the throttle body for increased low rpm torque, and you want to adjust its length to play with the torque a bit too. But, before that, just use a large pipe. I don't see any problems with using aluminum dryer ducting like others have.
