Ok, so I just installed the JLT RAI and it is great. But I want more power so if I went with the Mac 2.5 catback stainless steel, the C+L upper intake plenum, and the mac 75mm tb would I gain a fair amount of power? Would the "Stainless steel" exhaut rust? Will the plenum, tb, and intake line up and will the finishes match?

Your looking at around 10+ hp gain. Your not going to see much just from a catback and a 75mm tb plenum kit. The mid pipe is where you are going to see more of a gain. You aren't going to see any more power till you get a tune. Once you get a custome tune you will be looking at around 30+rwhp.
 
I noticed a difference (not huge) when I installed my 75mm tb and ported plenum. It pulled harder up top.

You wont notice much if any at all gain from just a catback. The mid pipe is where its at though. I reccomend an X pipe if you want to squeeze the most out of it. Mine pulled noticably harder up top after I put it on.

X pipe and Mac's sound great... here are some of my clips. UPR catless X btw...
