I have the F.I. LTH's and 18" Res SS CBE and can say too I love it, and Rasp is not that bad at all with the 18" Res cans. My only question is possibly switching to CF cans for that slightly exotic sound. Other then that, I couldn't be happier. I can tell you from a butt dyno that it does pull harder, and this isn't even with a tune. Can't wait to see it after a tune.
Not telling you to get F.I. or not, just an extremely satisfied customer giving a review. Take it as you will.
