Exhaust leak?

Exhaust leak? First time the car has seen measureable rain (more than just drizzle) and I get to work and i hear hissing from the exhaust and see some steam. So I look under the car and the connection from the headers to the cat is steaming pretty good. Is that a good sign that I have an exhaust leak there and need to tighten the bolts up? I've never seen/heard it do this before. Not sure if it is even anything to worry about.

Well there are no gaskets or anything there... so would it just be caused by the nuts backing out a little bit? I mean, how else could an exhaust leak start there? I doubt the heat would be enough to warp either side of the flange... its pretty thick metal.

You said it is flanged...if there is no gasket there, that may be the problem (unless it's a ball flange?). Mine were slip fit, problem was I could never get the clamps tight enough, so I ended up just welding them all together.
Try tightening the bolts, using a gasket and see if that helps.
yeah im getting really tired of my Y pipe ticking on the drivers side header/ Y pipe meets, im gonna get a X pipe put on and prolly have them tack the X pipe on and then band clamp it so i can take the X pipe off once i do my converter.

No, no no... the connection i am talking about is where the Y-pipe meets the catalytic converter... THAT connection has no gasket that I am aware of. The nuts on the studs that connect the flange of the y-pipe to the cat have backed out before, that is what Im thinking may have happened, not sure why it keeps happening tho...
I know what you guys mean with that slip fit... that has given me fits! I have already dealt with header/y-pipe connection problems. Those were fixed awhile ago.

interesting idea... ill see if it is even leaking first, if it is, i should be able to feel air coming out of there somewhere. Otherwise, it must have been just really wet... i dunno.

I have a header leak due to 2 bolts not being in because of 2 crossthreaded bolt holes on the passenger side. I don't know if I can heli-coil it w/o pulling the head, or if tapping it will do the trick.
