An exhausting exhaust fan

changed out the exhaust fan in my bathroom, I think the original fan wasn't rated high enough for the room. there was always so much steam in there when we ran the shower and I was worried about the problems that would cause down the line. so here's the pics from the project. 

overall, it was a simple enough project, but it certainly is hard work on the legs believe it or not. I couldn't figure out how to sit down in the attic so was in a perpetual half squat while working on this. 

found out there was a small size difference in the fans even though they are the same size on paper. so am having to patch that with some dry wall and putty later. 

I though the tubing was setup weird, but i figure its functional so I left it largely the same as I found it.
