I agree, the WOLO Badboy, and all similar permutations of the Nautalus (which are all identical) farrrrr outblast anything... but, keeping it mounted nicely, so it doesn't collect water, forces its location.. not to say it can't be disassembled, and pieces parts relocated using some rubber hose...
or, you could cut holes in your fairing and aim it frontways, out the hole, like the first guy that mounted one did... but that wasn't a sharp decision on his part...heheheheheh
