Water out the exhaust
Water out the exhaust I just installed my mangaflow last nigth and this morning i check the exhaust and where i bolted the exhaust, water dips outs. I checked for any exhaust link, but there wasnt any. what should i do? i dont want to weld it also.
my dad told me that autozone or a auto part store, sell a glue like thing that i can put around where the pipes connect to, to seal the leaks. what is it called and does it work?

Is it dripping where the new I-pipe meets the Y-pipe? Mine drips a little bit there too after a cold start. Not a big deal, it's not hurting performance any at all and if the leak is not big enough to be audible (mine's not) I wouldn't even worry about it. Actually, mine doesn't even show any carbon build up around the joint, it's gotta be just a tiny area where the pipes meet that isn't a water tight seal.
Anyway, if it's like mine then it won't even drip after the car has been running a few mins.....

I would not worry about it at all. The autoparts stores sell a "muffler repair kit", it comes with some little strips imbedded with some kind of fiber. The one's i bought almost looked like a fruit rollup 
When its put on a mufler/pipe, it heats up and hardens. I Placed one inside the bandclamp that connects my driverside header to the exhaust system to seal it up better. It crystalized and i damn near had to jackhammer it off.

its from all the bolt-on clams,all 5 of them. if there is a paste like seal, i will put it around the tudes. if not then i will leave it like it is. by the way, the exhaust sounds bad ***. you cant really hear it from the inside, which i like.

Don't...sweat it...lol!(stupid water joke?)
The small leaks where they're clamped will most likely seal up after a few weeks from small carbon deposits. If it bothers you that much, crank your clamps down some more.

Don't worry about it. Condensation will always build up in your exhuast. When you drive your car for long periods of time and the engine has been at operating temperature the water will evaporate when the exhuast system stays hot for a long period of time.
If you drive your car for short distances and there isn't enough time for the condesation to evaporate then water will build up. If you have a small leak then the water will have a way out of the exhuast system and you won't have to worry about water inside the exhuast.

Basic chemistry, C7H16 or whatever hydrocarbon you are running plus lots of O2 is going to give out CO2 and H2O plus your usual cat suspects CO and NOx plus a tiny bit of C (or lots in a diesel)
Its just normal that the air is hot so no condensation occurs, winter lets the condensation work and precipitate out the water from the exhaust which is ALWAYS there. Just put your hand close to your exhaust you will get moisture on it.

As stated above, your converters convert to H2O, which when at full operating temp (or warm day), is so vaporized that you cant see it. It steams as it condenses in the catback, which you can sometimes see, and even turns back into a liquid if the temperature is low enough to condensate all the way
I had problems with small leaks with my true dual setup. I used this paste stuff called thermo steel. I tried a few other kinds before that and they all lasted about a month then flaked off. This stuff is working great though. You can get it at autozone

I've seen water come out the back with a blown head gasket.
