Today I had the car idling and I noticed condensation in the tail pipes, little spots of what I suspect to be water gathering at the base of the tip and then getting spit out into a little puddle behind each tail pipe. I hadn't noticed this before when I was running ORP's... I just recently swapped in the cats so I have no idea if that has anything to do with it. Is it normal for condensation to form like this? Does it have anything to do with running cats vs orp's? Should I be worried at all or is this normal? I was thinking it's possible that condensation could build up in the cats with it being a bit humid outside. I don't see any noticeable difference in performance, although since I put the cats on about a week ago, whenever I shift hard in the higher rpms I get a little pop. I had gotten that with the orp's from time to time so I am hoping I shouldn't be worried.
Any insight?
Just an FYI- my mods are stage 1 heads, 218/224 comp cam, regular boltons along with flp long tubes and slp loudmouth.

 

This should not be a problem at all. One of the bi-products of combustion is water. Just don't drink it.

 

Totally normal Erin...
Nothin to worry about sweetie.........

Yay! Thanks <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

Erin, water and c02 are normal by products of combustion. Nothing to be worried about.

 

That's what cats do - they convert unburned emissions into CO2 and H20.

You should not, however, continue to see steam/condensation after the car is warmed up. Steaming out the exhaust after the car is warmed up could indicate other problems, like a blown head gasket or warped head.

Mine was steaming from leaking coolant into all 8 cylinders from both heads being warped .004". (Chris Johnson also just went through something similar).

Best of luck,
