I will keep you posted. My plans are to work from here to try to figure out a better solution for a pre filter on these things. I purchased a Warrior and it is ok, but I don't want to cut the plastic. I would like to get a solution that exits the side grill opening like the Honda separator. In another post someone mention air flow concerns. Ha, if you look inside the Warrior pipe there couldn't be any dirtier application. It is nothing but a bunch of PVC like pipe glued together. I have a couple of ideas, but I have to tear it down to see if they will work. Flim at 10...
