When I got home today and shut off the car, a bunch of hot water kept hitting the exhaust and causing a hissing noise and a little steam cloud. It is an aftermarket invidia carback exhaust that I had installed 2 days ago. It never used to do this so I imagine this has something to do with that install. I believe it is just AC condensation but I still don't know how it's getting to the exhaust. I will post a video in which you can hear the hissing shortly once I figure out the format, any help or ideas on what could be causing this are much appreciated.

 

It is most likely AC condensate and if so, honestly I wouldn’t worry about it.

some days are more humid then others and will generate more condensate.

My only worry would be if you happen to have a valley plate leak and that is what you are hearing dripping on the exhaust.

Other wise I wouldn’t worry about it. It is only water and won’t harm anything

 

When coolant burns, oh boy do you smell it. It is one of those smells that instantaneously makes you want to vomit and sing some lonesome blues. It is absolutely horrendous, and not to mention if coolant is dripping that much, there would be a fairly large (if not massive) puddle under the car. As brendanf said, it is most likely just the AC condenser.
