I had an AFE high tuck on my JK. It was awesome. Really helped to hear when to shift. For the JL, I went Injen because there was a lot of reviews about the drone the AFE produced on the JL w/ 3.6. The Injen has been great. No drone and still looks new after 18 months. Just butt that pipe right up to the indexing pin and crank the clamp down. I spoke to Injen about notching their downpipe because the pipe slipped a bit after initial install and they said no need to so long as I tightened the clamp up. Sure enough, I went back and tightened it down more and it has never slipped since.
BTW, I found it for $400 online and had Quad price match it for me. I still think $400 was too much but I knew that I wouldn't find a better deal.
