Re: condensation/water in exhaust I think it's fine however I may be wrong
Some of the original exhausts had a small hole in the torpedo silencer to
Let any water out (iirc)

Re: condensation/water in exhaust If I leave my 2CV ticking over on my drive it leaves a damp patch where water has literally blown outa the exhaust.
If it bothers you that much .....do as I do with my motorbikes,and squirt some WD40 [or preferably one of the cheaper alternatives] up the exhaust after a short run.
A long drive of course will heat the exhaust up so that most of the water evaporates anyway.
Edit .....and dont try this trick on a modern car,it'll prob'ly "fubar" the catalytic converter up.

Re: condensation/water in exhaust Water is a natural product of the combustion process and therefore nothing to worry about - just go for a long drive.

Re: condensation/water in exhaust Actually blackjack my Aircooled VW Bug used to suffer from Mayo in the oil filler and there was a special trap in the Air cleaner box to catch this. Mayo in the oil can happen to aircooled cars as well as watercooled ones and can be due to moist air being sucked into engine (eg rain) , water ingress (through fording) and short runs where the oil has not got hot enough in damp environments (eg Great Britian).

Let any water out (iirc) Quite right James. If you look at an original Citroen 2CV exhaust rather than a pattern one, you will see that the long tailpipe also has a 4mm hole at the bottom of the cranked section to allow water to escape. Some original swannecks also have a 4mm hole at the lowest point just prior to the torpedo. Water is usually more of a problem in the tailpipe as this is the last part of the exhaust to get hot and so evaporate the trapped water. This is also why the back box is almost always the first part of the exhaust you have to replace.
