So first of all let me start by saying this thing does have a whistle noise even though it says its quiet. I do have a aftermarket intake and I'm not sure whether it makes it whistle more because of all the air coming in faster. Also I had to cut some plastic to make it fit because of aftermarket intake. Now for the mpg/hp/tq gains as far as the mpg I'm not too sure on that but I do have better throttle response and my truck gets going better than usual my truck does feel like it has more power.

Simple install, has that typical whistle between 2,500 and 4,000 rpm. Note: didn't whistle at 1st but did after I seafoamed my truck to improve performance. Definitely pulls hills better. No need for the expensive metal ones.
