Is it normal for fliud to be dripping out behind the muffler?

I have a 2006 SE 4ltr automatic and I've been noticing what looks, smells, and feels like water.... I didn't taste it though. It's coming from behind the muffler where it is connected by bolts.

Here are some pics.

This first one is inside the shovel, the last one is the floor under the shovel.

Thank you

Yes, that is normal condensation. No worries.

Everytime I see that drip I feel compelled to crawl under just to make sure it's water lol.

Mine does the exact same thing. Comes from the factory weep hole that's placed in the muffler to allow condensation to escape and the water ultimately drips off that flange. I freaked out the first couple times I saw mine doing it lol.

Mine does the same. I was a little worried the first few times I saw it before I figured out it was just water.

This is correct. As with all TJs, yours left the factory with at least one catalytic converter. By its very design, a catalytic converter converts carbon monoxide and unburned hydrocarbons to carbon dioxide and water vapor. As you might guess, this water vapor would cause the rest of the exhaust system to rust very rapidly from the inside out. In order to prevent this, most manufacturers put a small drain hole in the muffler so that the collected water can escape without doing any harm; you can see this hole in one of your photos. The puddle you see is actually a good thing--it is helping your exhaust system live a long, rust-free life.

Oh, and:

No kidding! You know how they always say not to leave traditional green coolant out because pets will think it is sweet and thus they'll drink it (and die from it)? I can vouch that it is sweet, but in a really nasty way.

I knew it had to be water (I secretly did taste it...) Just was confused because their is a hose that lets the water out when the A/C is on. Didn't think their would be another place for water to come out. I guess That's good news if I'm ever stranded in the desert.

This reminds me of when my college chemistry professor warned us:

"Rule #2 of chemistry is never drink what you make!"

See the black streak coming from the black spot at the front of my muffler? That's the drain hole I left when I welded the muffler in..
