I’ll be okay with it if it only gets loud at high revs because I can control that, I just don’t want drone or loud startups and idling.
I agree with all of this. Just keep the *high-flow-ish* OE secondaries so you won't have to worry about smell, plus they will really help keep it quiet. That said, I honestly just don't see you getting more than 5 whp by changing the cat-back exhaust. So, is it worth it? For me, the sound definitely would be. But if you are trying to stay as stealthy as possible, then I dunno...

Also, what is the benefit of the AA mid-pipe vs. the stock mid-pipe?

Hmm, perhaps there is a way to "defeat" or disable the cold-start scenario? hassmaschine ?? New Mustangs come with a button to do just that. Don't wake the neighbors! Personally, cold-starts are my favorite.
