The BBK's may give slightly more power than the Ford, but will also stay better lookin for longer and probably fit up better. As far as x-pipes/h-pipes, h-pipes have more of a muscle car sound, and x=pipes sound smoother/different and offer a little more (usually) gains than an H-pipe, but are usually more expensive. For hte hanger, maybe try dropping the lower hanging tailpipe and bending the hanger slightly so it'll pickup. Mine did that, it also stuck out farther on one side so I cut one shorter, then eventually took them off and went wiht turndowns. If I were putting on all new exhaust, I'd go with BBK full-length headers, BBK or Dr. Gas X, Bassani/magnaflow/flowmaster (not sure which one) w/turndowns.
