One thing to keep in mind is the size of the exhuast can make your torque band change a bit. When I had my 7.3, the change from a 3.5" DP, with 4" back to a full 4" system made a noticeable change to my low end torque. I'm not sure if that's the same on these 6.0's or not, but I've also hear that the 6.0's run a little better with some back pressure. Your mileage may very.

Just to put my .02 in. You should stick with a 4" exhaust. A 5" will actually hurt performance a little, and is not necessary unless you have well over 500hp.
Also the way most people do it is get an onroad exhaust (cat and muffler) then just put straight pipes in place of the cat and/or muffler so they can bolt them back up for emissions testing. You will see the highest drop in exhaust temp with the muffler and cat removed.
