i didnt feel that much of a torque loss (if any...) from the stock manifold going to the header i made... it had 1.5 inch pipes on it and it went to a 2.5 inch pipe... way to big i know but once you got up a bit in rpm it was fine... and if your wanting more power chances are you dont drive it nice anyways... just done lug the motor around everywhere and you will be fine... rev it up and have some fun lol...

Get them. If they are too big, you have a perfect excuse to change the camshaft for some deep breathing. If you are air/fuel starved, then check the yards for some twin laser carbies.
