YAY!! I found something! Now I can start building.. But there is something called a muff (word?) and a "bøsning" (word?). Both are reduction pipes, but the "bøsning" is cheaper (wtf :? ?). What's the difference (except for the price)?

Okeydoke :)

A *muff* appears to be a reducer and a *bøsning* is a bushing

You should use the bushing because reducers are usually DWV, but yours looks like it's pressure rated.

So I would still use the bushing as it's cheaper and looks better.
