I have the Lightning style w/ LT Headers, cats and performance connect also. Hands free works just fine but it did have a head rattling drone between 1200 and 2000 rpm for about the first 7000 miles. Somehow the system has "settled" in a bit and is not too bad now that I have about 10000 miles on it. I don't get to drive on the highway much but it does seem to get better once everything is settled in at highway speeds and in 6th gear. I do have one suggestion for you should you choose to accept it. I also have the blackout thermal ceramic coating on the tips just like yours and the leading edge of mine is getting beat to hell from road debris, etc. If I had to do it all over again, I would have some sort of a mid-flap installed beneath the right running board and ahead of the tips so as to protect them from chipping. As it is right now, I'm going to have to have mine re-coated soon as they are beginning to look terrible. The picture shown is an old picture but you can already see some of the rock chips developing.
