Water from Exhaust@Cold Start.

Hey peeps, how is everybody doing ?

I know that it's normal for a bit of water from the exhaust at cold start, even though I am not sure why that happens. I heard somewhere it has to do with your a/f ratio. Meaning your a/f ratio is right. Please correct me if i am saying something stupid.

However , I have 2 exhaust leaks which I need to fix but I was just wondering if its normal for this much water to leak from the exhaust and why it happens. Below are pics of my cell next to the leak to compare. Sorry for the Noob question but its really curious to me.

Header/exhaust leak.


Midway Exhaust leak.


Spittin water out at least 2feet from the muffler. Bad pic but all that is water.


Thanks for the help guys and I hope this isnt a stupid question.

Its perfectly normal... . Its condensation in the pipes after a static period and subsides after a minute or so of warm up...

No...

but depending on where they are, they will emit noise and exhaust gasses that might not go where they should. You don't want gasses to go into the cabin.
