So my tC is supercharged and I have a faulty catalytic converter. I'm waiting on the dealer to get me the new one and I noticed my exhaust tip drips a weird fluid. I asked the mechanic about it and he said its simply condensation. Is this true? I don't think I've had this stuff dripping before... Can anyone shed some light here?

Here are some pics and a video:

I'm pretty sure fluid coming out of the exhaust is condensation from using your A/C in humid areas. not exactly sure how that condensation gets in the exhaust but it does. it's just water, and if you have cat problems then the inside of your exhaust is probably pretty dirty so the water mixed with that crap gives you the diareha look.

>lol. cool, thanks. i need to start trusting my mechanic a little more. i mean, dont get me wrong he knows his stuff (he has 2 1000+ hp mk4 supras and a 1jz tt sc300 - he even gave me a ride in it. lol. pretty weird, but cool). it's just since he works for a dealership - i have a hard time trusting them. plus, all the horror stories surrounding the trd supercharger installation makes me even more paranoid. but thanks for the explanation. that makes sense.

even if my a/c is not in use (which it wasnt in the pics and video since it was a cold-start), could it be possible to have condensation somehow?

Yep. The byproduct of catalytic converters is water, so that creates condensation inside your pipes. If you leave your car running and look at the muffler, you'll see that water drips out of the muffler.

its just condensation from the cold exhaust pipes getting heated up quickly. my car does the same thing, and i dont have any cats on it.

you can see it in this vid of my car.
