So you can open em up and let em drain or use it as an excuse to replace them ugly cans later when they rust out!

Though that will take awhile to happen....

yeah i guess i will have to open them. i also have black grim looking stuff on the bottom of the mufflers. ill post a picture.

WOW, I just checked my mufflers and both had water (over a cup in each) in them. Its very easy to check....crawl under and youll see a very small hole on the forward part of the muffler. Stick a thin nail, or even a toothpick, into the hole and wait for the waterfall to start. My car is less than a month old and 2K miles so I think EVERY Camaro on the road (with the stock mufflers) will have this problem.

I would suggest actually drilling them out further. If they can plug up at this diameter this easily, I would drill em out to 1/8in or so if you are keeping them and not swapping them out for something else or eliminating them....

Im changing the amount from 1 to 2 cups of water in each muffler.....its been over 30 min since they started to drain and they are still dripping water, not a steady stream anymore but still coming down. Everyone, please check your stock mufflers!!!!

Moorepheus · 04-11-2010, 10:06 PM

my holes in my stock exhaust were not blocked and there is no water in my exhaust. 1400 miles.

rd-camaro · 04-11-2010, 10:32 PM

checked mine earlier today and it turns out they werent plugged up!! the holes are unplugged and no water is in the mufflers. its funny though cuz i never notice and water dripping from the mufflers.

When I checked mine last night there was no water, I used a 2.5 inch thin nail to poke up through the holes. However I did notice a long time ago that there seemed to be some water on my tarp after I had been running my car for a while and pulled my car back in to park it.

It never really sounded right, then a few thousand miles ago it made a vibration/rattle noise between 2k/3k RPM. The new exhaust sounds 1000% better.

My drivers side had about a quart of water in it when I removed them.........Problem solved

ZED SLED · 04-13-2010, 11:56 AM

My stock mufflers at the landfill, probably full of water

i checked mine today. had a lot of water in one, drained for 30 minutes, the other for about 10 min. Not happy that it can clog that easy.

I hope someone from GM is reading this and posts a response.

See pic below, as you can see the right muffler is still draining and did so for a long time after i took the pic.

If you drive the car long enough everytime, the exhaust system should heat up enough to drive off any water.
