I definately believe you were asking a legit question, especially since you took the time to post pics. As was stated, totally normal. Temp., atmospheric pressure, have everything to do with the condensation your system is pushing through as it warms up. You have a tight system which is a good thing.
Just one more question, the water is coming out of the muffler where the dent is, not the pipe, is that normal too?
The only thing I see in the pic. is the drain hole that is manufactured into most mufflers. I don't see a dent just the normal contours of a JK muffler. Condensation is going to come out there and the tail pipe.

I do not consider myself a smartass. I point out the obvious, search for the truth, and speak fluent sarcasm. I am, by experience, an accomplished curmudgeon.
If this makes you feel any better I once had my own auto shop (engine rebuilding, etc.) many years ago and I though that my exhaust system was leaking (water under my Jeep) too. The dealer told me that the exhaust was built that way and was normal. I’m well aware of it coming out the exhaust pipe but not in the middle of my Jeep. Sometimes you just have to ask.
It can drain quite a bit at first startup in the morning. When you parked it the evening before, the exhaust was cooking, and as it cooled, water condensed out of moisture in the air inside the pipe. This water, in addition to the normal amount produced by the cats is pumped out of the water vent in the muffler.
The amount of thought that Chrysler put in the JK muffler surprised me, as the muffler would rust out quickly if that water was allowed to stay in. I'm trying to find a schematic of my edelbrock muffler to drill a weep hole in it. That hole also allows any water to drain that comes in the tailppipe during deep water crossings if you end up stalling the engine.
