    <font color="green"> Water droplets in the exhaust is a sign of complete combustion. This is a good thing. I suppose you could try to de-tune it until it goes away. /forums/images/graemlins/eek.gif You could also change your exhaust tips so they point down... /forums/images/graemlins/rolleyes.gif</font color>

    Actually the water is caused by the chemical reaction is the cats. More than likely the soot is just burned oil.

    <font color="green"> My exhaust shoots a good amount of water when it's warming up too, and I don't have any cats. The soot is just from inside of your exhaust, there's always lots of soot in there. Since the water mainlyu shoots out on warmup, it just washes out some of the soot that built up from the last time you ran it. I get a little bit of soot in the water, but not a whole lot. If you're putting black streaks on the walls from all the soot then you might have an issue. /forums/images/graemlins/eek.gif </font color>

    It's not just because of the cat converters.

    Mine shoots out enough water when its started to make a small mess too.

    Just another reason not to drive short distances constantly, if you don't get the exhaust hot enough to evaporate all the water, you'll end up with a bad exhaust system.

    You could drill a pin hole in each muffler. I was told that if you mount flowmasters vertically, that you should drill a pin hole in each one or water would collect in it. The muffler on my '02 GMC truck has a small pin hole in it towards the bottom of the back edge. Just an idea.

    condensation of exhaust in cooler temps is normal and will go away as the exhaust system warms up to operating temp

    So are you just getting water buildup when it is warming up or is it puffing black smoke like Winston Churchill? It it is just water, its normal...EVERY combustion yields both carbon dioxide and water. If it is puffing black, it is probably just a matter of a tune up and running some BG 44K thoru it...
