197 exhaust tips but not usual question...

got the ebay exhaust tips fitted today quickly, went for a quick spin, decided to remove and refit
with a clamp,
on removing some liquid came out is this usual?
also once car had been turned off fumes were still visibly escaping the tips, ?
 
Pretty normal.

Water will no doubt get into a clamped-on tip. The fumes are partly the water being evaporated by the hot exhaust and partly exhaust gases still working their way through the system.
