Water from the Muffler?

[Tobes]

I have not really noticed this before and am not sure if this is normal?  I noticed a puddle of water in my garage after parking the truck in it (it had not rained in days and I have not used the A/C) so I looked for where it came from. I noticed water dripping from the muffler.  I can't say that I have ever seen that much come from there.  It would seem that at the least there will be a rust problem with that.  Has anyone else had this?  Is this normal?  I don't remember any previous vehicle of mine doing this.  Thanks

Mine has done this since new

has something to do with the catylic converter, convert's co2 and h2 to co and h2o or some s*%t,

It is nothing more then condensation. Depending on the weather and the length of your trips it can be quite a bit of water.

Thanks for the quick replies...  That is what I figured.  It just seems like a lot more than I have seen from other vehicles.

A short trip will create more condensation because not enough heat is created to evaporate the water.  There is a weap hole in the muffler to let this water drip out so it won't hold all the condensation.

 

You'd be amazed at all the water that comes from the tailpipe as the truck is warming up.  There is a red light about 6 blocks from my house, and if I have to stop for it, I leave a trail of water on the road about 20 feet long out of the exhaust.

My 02 Silverado does it some but I have seen some vehicles that have a lot of water soming out the exhaust!

From Delphi:

 

Catalytic converters typically consist of a ceramic or metal honeycombed monolith substrate that carries precious metal catalysts. The coated substrate is wrapped in an intumescent mat that expands when heated, securing and insulating the substrate which is packaged in a stainless steel shell and fitted into the engine exhaust system.

 

As exhaust gases pass over the catalysts, they promote chemical reactions that convert pollutants into harmless gases and water. Hydrocarbons combine with oxygen to become carbon dioxide; oxides of nitrogen react with carbon monoxide to produce nitrogen and carbon dioxide; and with hydrogen to produce nitrogen and water vapour.

 

The catalyst formulation, which promotes a faster chemical reaction at a lower temperature, is usually a mixture of the noble metals platinum, palladium and rhodium, and sometimes other catalysts such as the rare earth ceria.

mine has two small holes in the bottom of the muffler that look factory . Wonder if that is to let water drain so it wont rust out .

Just as shaners said.....they put the weep holes there for a purpose.  Short trips are killers.  That is why I disagree with Corvette guys that winterize and occasionally start their cars. It takes a good amount of time and a load to get rid of the condensation.

don't sweat it --it's normal

I know that every flowmaster muffler I have ever delt with has had those in them on both ends... Kinda cool to know that my stock muffler might too... Ill take a look later...

[City_Slicker]

Its all good. Mine does it too. If you convert to another muffler like a flowmaster is it equipped to handle such?
