Default Exhaust dripping water?

I just recently installed Invidia exhaust and I'm noticing a lot of water dripping from my exhaust. Is this normal? or should I be concerned?
I noticed the water drips and a faint white smoke during a cold start and parked after a drive. Also when I'm decelerating I hear a pop noise?Anyone else having this same issue? any help would be greatly appreciated.

Is normal for my coolant to drip out of this hose?

Seems like it might be normal condensation. Maybe someone else will chime in.

99.9% of the time, it's just combination condensation.

if it smells sweet (like maple syrup) or if your exhaust includes light colored smoke (burning oil) along with the dripping water, then you're going to have a bad time.

cold start smoke is normal, your cat isn't up to operating temps yet.

downshift backfires are also normal. dshifting makes for a slightly richer exhaust; that coupled with hot headers makes for a little pop

coolant system probably should not be leaking. unless that's not coolant. does it smell sweet around the leak? it might just be condensation

Water/moisture is natural as part of the combustion by product. More noticeable on colder days.
The coolant part not too sure on that one.

thanks I just got my car service recently at the dealer. I'm guessing they poured too much and didn't clean it afterwards.

I appreciate the input, I'm more at ease now lol. I guess I've never notice the water until the new exhaust install. I'm assuming that's why the stock exhaust is always stained.
The liquid has no smell from what I can tell, and it's clear like water.

Would adding a Invidia mid pipe stop this issue since it will remove a cat?

I just notice today that on the edge on both exhaust canister drips water? Can any other Invidia owner check if your exhaust drip water from there?
