Muffler has a hole

[H3 Hummer]

I noticed something dripping from underneath my H3 - it was quite dirty so I took a closer look. The drip was coming from the muffler - it is most likely condensation dripping through a hole.
I already had an appointment scheduled for next Tuesday for my oil etc. so I called them and told them. The Service Advisor told me that is normal - I said in the middle of the muffler? He said yes.

I know it is an actual hole because I can slightly feel the air coming through - what I don't know is it made to do this like he said? Upon closer review it looks like it is supposed to be there.

The area is right before the leaf springs - the muffler is expanded in this area.

Weep hole, its supposed to be there!

It looks like your diff has a weep hole to


The weep hole is suposed to be there to let condensation drip out.
It looks like there is a second hole in the middle of the muffler?

Looks like your H3 has seen some trail use too!!

What's up with the wet spot on the diff, it's not leaking is it?

I just noticed I have a transfer case leak at the output shaft seal w/7k miles on the truck.

As everyone else says...weep hole. But, that is not a muffler, it is a resonator. Muffler is at the rear and most likely has weep hole(s) too.

That's also normal.

GM uses the cheapest seals they can buy. Always have.
