I just received my Ripp for my 2012 JKUR and it should be going in Saturday. I'm pumped about it I'll let you know how it goes. I also liked the idea that a twin screw SC because it kicks in at a lower Rpm but I would rather go with the manufacture that has the best support due to the most kits on the road.
Welcome to WAYALIFE and good luck to you with your RIPP. I have personally known several people with one installed on their Jeep and none of them impressed me. One flat out removed it from his Jeep because of all the problems he had with it.
