Deeeeep breath, bro.

It's condensation - perfectly normal.

You live in a humid climate. Hot gasses going through cold metal pipes = condensation... it puddles in the bottom of the pipes and mufflers, and "spits" out when you rev.

By the way, any way you could do away with capitalizing every word? It's kinda weird...

Welcome aboard, y0.

Also, your idle is a little high at 1200 (warmed up). Several possible reasons for this, but I'd recommend you read up on all the maintenance procedures for the Q, then start small - You got a good car, but she's high-maintenance.

I think most of the water is a bi-product of the fuel combustion. During combustion the carbon (C) combines with oxygen (O2) to produce carbon dioxide (CO2) and hydrogen (H) combines with oxygen (O2) to produce water (H2O). As a result, an efficient running engine will produce water, even when the humidity is zero. An inefficient engine will produce carbon monoxide (CO) and less water.

^ Good point.

However, that "efficient running" engine will likely burn off any resultant water vapor before it can visibly exit the tailpipe.

Massive area of exhaust system allowing the water vapor to condense ........the piping is colder by 50-100F in winter at cruise there is so little heat generated compared to WOT less tah 10% of WOT amount.
