I've noticed a few times that water drips out of my truck's tailpipe. Is that a normal thing? Where does the water come from?

Maybe this is why my stock muffler rusted through at 35K miles...

Thanks,
Jason

Damn only 35K on stock exhaust?
Is warranty going to cover it?
If not look into aftermarket system.
Water comes from condensation in the exhaust system when you shut off the engine.
This is normal depending on where you live.

 

When you see the water dripping..is your engine running? Water is a by product of combustion..and is quite normal. This is why most exhaust systems rust from the inside out..the water sits in the low areas of your exhaust and begins to form rust..which will spread and eventually cause a hole in the system.

 

Thanks Guys.

Just to clarify, I see the water dripping immediately after I turn the engine off. It may be dripping when the engine is running, but I'm not looking at it then.

My stock muffler had a small rust hole on the back end at the bottom. When the engine was running, I noticed that water and exhaust was being spurted out the small hole.

I took this as an opportunity to install my new Gibson swept-side catback system!!!!

I also had noticed the water dripping from the tailpipe after I bought my truck. I asked around, and I was told that it is normal it to be dripping water, so I haven't thought much about since.

You need to run the vehicle long enough to let the pipe get hot, which stops the production of condensation. When the exhaust is hotter then the inside surface of your exhaust system, you produce condensation. That causes condensation everytime you start up the vehicle, in cold weather, you produce more. If you run the engine long enough, it will empty the water from the low lying areas, which is why you should not just jump into your vehicle in the winter, drive 1 mile and stop it. That will rust out your exhaust quickly. In the summer, you produce less condensation because the pipe and the exhaust stay at a closer temperature which produces less condensation.

 

Water is a byproduct of the cat.

 

V10man, well, my 1970 lemans SS convertible with dual exhaust pumps out tons of water and it doesn't have a cat.

I have heard that the water, even though it's bad for the exhaust(rust). It is a sign that your engine is in good condition. My .02

On a clean running engine c02 and water are the only things that come out of the exhaust.
Ford puts a hole in the bottom of the rear face of the muffler to let the condensation out. make sure the "rust hole" in your muffler is not the weep hole before having a new muffler put on.

 

EVERY vehicle produces water/moisture out the back of the tail pipe! (especially when you first start the engine)

It is 100% normal! The burning of fuel in an engine produces H2O as a by product.

My 5.0L Mercruiser Alpha 1 has a ton of water comming out the exhaust. You sure it's normal??
