Torque loss with offroad mid-pipe?

I've noticed that most of the guys with 03's are running catted mid pipes. Now i realize that you have less crap to deal with with inspections, service dept., police etc. when you have cats in place. My question is- With a supercharged engine is there a concern with retaining a certain amount of backpressure for optimal power/torque? Would this make an offroad mid-pipe a bad idea with a catback?

I have a MAC prochamber and a Densecharger sitting in the garage until the engine has another 1000 problem free miles on it. I would like to go with either a Borla Stinger or a Magnaflow cat-back.
