Great idea for a thread Matty, thumbs up
How much water is coming out of that pipe you are talking about? If it's the silver looking one then I would say that the silver is just a sleeve to help protect the hose as the turbos at work have them for the oil return line. Also if you can try and check the bolts holding the hose/pipe on and feel for a leak as a washer or O'ring could be worn and causing a leak.
As for the exhaust, it looks like part of the pipe is missing because it should just bolt straight back up from what I can see but i'm no exhausr expert.......not all exhausts bolt up the same way. Hope this info helps bud.
