Weep holes equinox 2013

Anyone know if there are weep holes in the muffler on the 2.4 2013 equinox? Rained heavily yesterday and today it's in the 50s was idling the car for 20 mins or so and saw a drip coming from side of muffler. Just wondering if I have a hole or if it's a weep hole or something. It's definitely condensation has zero smell.

Can't say for certain on a 2013, but I just looked at the transversely mounted muffler on my wife's 2017 2.4 and I saw no "weep" holes. When you say side of muffler, are you referring to the side that faces the rear as it is transversely mounted? On the previously mentioned '17 the side that faces rear has the seam found on most mufflers other than glass packs. The seam is an early rust out area but perhaps you were seeing moisture dripping from up higher?

Im almost tempted to say that all mufflers have weep holes.
right at the bottom part- where moisture would condense.
on DI engines- the area around the hole will be black from carbon.

It's on the side where tail pipe connects to muffler. A family member has the same year car as me and they have a drip from exactly the same spot. So I'm going to assume it's normal. That or we both have leaks in the same place.

My 2014 has a weep hole, maybe only the 3.6L has the hole.
Probably a bigger muffler to.

I think weep or drain holes are the norm now .

If you don't drive your car long enough to warm up and dry out the exhaust system, condensation accumulates and puddles in the lowest point--usually the muffler. Some mufflers come from the factory with a weep hole to let the moisture drain. ...

My 2013 Equinox created its own weep holes on the muffler under the passenger side floor (not the transverse one in the back) when the entire seam rusted out at 40K miles.

I can confirm a weep hole, or drain hole on our 19' terrain. It's amazing how much water comes out of that hole while idling in the garage. At first I thought something was wrong until I looked closely and saw the hole

Ive seen cars- at stop light- that are still not fully heated up (exhaust pipes cold)
that when they accelerated from the stop- water poured out the muffler.

My 2014 Terrain Has "Weep" Holes on Both Mufflers. You Have to Look For Them With a Flashlight & Mirror. I Always Clean Out the Hole With a "Pipe Cleaner" (or) Some Like Item. It's Normal on Warm-Up to Get the Byproduct of Water From Muffler Weep Hole.
