I haven't tried Air Flow Systems yet, actually truthfully never heard of them before until right now. Will take a look into them and see what turns out there.
I did see that Ramchargers carried them but I am not sure about the blue hoses yet. And honestly, I don't really know what color I am looking at getting. I guess you can say I am window shopping right now. Trying to find different ones that might catch my eye! I have a feeling that we might land up going with the basic black hoses all around. Just figured I would sprouse it up a little bit with the different color.
I have to go back and look to be positive but I believe we need to get 3.5" down to 3"
