Last night while under the truck changing oil I noticed a puddle of water on the floor, upon further inspection it was water leaking out from the stock exhaust clamp after the 2 into 1 on the stock exhaust. Is this normal or should I be concerned?

Thanks!

 

Normal on my 06 anyway.

 

hmmm , usually my 07 f150 will spit some water from exhaust tip at morning when driving for the first few meters... just bearly few drops... maybe it's some Intensification?

 

Very normal. Clamps usually will leak water, and condensation forms all the time in these trucks.

 

Normal.

When a Catalyst converts carbon monoxide to carbon dioxode, the by-product is water.

When the exhaust is hot, this water travels out as steam/vapor (which is why there is little carbon in modern exhausts as this steam cleans it out).

The water you see coming out is usually at idle or at startup when the exhaust is cool enough that the water is not turned to vapor. This is especially true at startup when you will blow out all the water buildup from the last run as the exhaust cools.

BTW - this is why all stock modern exhaust are some form of stainless - they all have condensation buildup that will rust out a non-stainless system fairly quickly.

 

I thought it was normal to have a little coming out, but just seemed like a lot to me.
Thanks for taking the worry out!

 

Jax 150 is correct.
Incidentally when I install my exhaust systems I intentionally add a "bleeder" hole at the lowest point of the muffler to allow the system to purge condensation. The condensation also includes carbonic acid and other acidic compounds that eat or rust out the muffler and pipes from the insides. Most quality exhaust tips include a small "weep" or "bleeder" hole at the base tip to allow condensation to run out.

 

Mine have that whole, I partly figured that's what it was for. Thanks for mentoning that

 

haha i just had my neighbor driving behind me pulling out the neighborhood and he came up next to me and said you have an some water coming out your exhaust and i just said yeah it happens in the morning time.
