No, you do not need to adjust for the MRT...
BTW... mufflers are not taken into account when your tune is made...

I'm a little dense, so you'll have to excuse me. 
Let me put it this way. I have a Flowmaster AT muffler on now, and listed it as one of my mods when I bought my XCal2. What I'm asking is, is the muffler taken into account when the tune is made? Because I assume that, if it is, I will have to have my tunes adjusted if I get the MRT.

No you dont need one. I dont think theres any exhaust that would need a retune to run i think its just tuned for a stock muffler when you buy the tunes and tuned for aftermartket if you replace it.
