If any of you are looking for a long tube style CAI, I just got my 2011 R/T back from stack performance where they put on their "bullet" CAI. I had to leave it for a few days so he could mock up a new bracket so it fits the 2011's but now he has the template and can make more real quick if needed.
It sounds great and throttle response is much sharper. Dunno if I picked up much HP but my MPG's went up by 2 or 3, I was avg'ing 29-30 mpg on the freeway
