i have a self-installed AWE, and to me, the clamp looks like it needs to be slid over and tightened. the clamp has about a 3cm range of adjustment. mine does not do this and did not require sealant or paste. it does blow that black liquid out of the tips however.

This would be correct. If my recollection of high-school chemistry is still somewhat accurate .....

CxHy+O2->CO2+H20

It's the same thing as seeing water drip out of a minivan's tailpipe while at a stoplight. The only difference is that while you've got a straight shot front-to-back out of the mini van, on a rear-engine'd Porsche the exhaust is a series of tight bends which encourages condensation of the water molecules. As mentioned, it is not a problem that AWE should address. Maybe a little loose on the exhaust clamps. If clamps are tight, then perhaps a discretionary amount of sealing paste is called for.

Nope ... not IMO

+1 ... my experience (of this) is from the tips upon initial startup and not the clamps around the exhaust itself ... I think either the clamp is not tight, or the
overlap of the connecting pipes is a little off...

I would start the car (with a cold exhast) and ensure that there is no blowby around those clamps ...

No, the water in the exhaust comes form the combustion of the gas. Seems strange I know, but water is a byproduct of the combustion of gasoline.

Thanks Larry, I will check the fittings this week.

Yup. No where else for those hydrogen atoms to go. Serious brain fart on my part.

Yes, correct, except that it doesn't account for the soot.

i took a look at my AWE last night and confirmed I am not getting any leaking at all as in the posted photos. happy to shoot some pics of the way my clamps are positioned if you can't find resolution.

cupholder leak. Gotta take it to porsche and pay $5000 to fix it asap otherwise the engine will blow..

A/C ?

+1 as I recall part of the AWE is slotted ... I wonder if the clamps are either not completely covering those slots or they are not tight enough resulting in leakage (never a good thing) when the engine is running (forced due to pressure in the exhaust system)
