i agree it shouldn't have anything to do w/ warranty, i've had a few dealers buy them from us and put them on there. i'd also highly suggest the Airdog over the Fass, we've delt w/ both and already the Airdog has outsold the FASS kits. also they have a lifetime warranty and great support, you will start to see more and more of them in the near future, we will also be doing something with them as well.
