[s-cars] July 4 good time to replace clutch :) Whats leaking?

[Ivan Demkovitch]

Folks,
 
Made some pictures of under car.
 
You can see transmission leaking past driveshafts. Where it coming from?
I checked - everything dry above transmission
Also, on first picture I circled bolts on exhaust. Is that a place I have to disconnect?
Those look like M6, not M8. Correct?
