Easy install installed it last week I already took it off !!! It makes a very loud and annoying whistle did notice a little extra go when I stepped on the gas

This works as advertised. I noticed an immediate difference in throttle response without the whistle. (my wife has not complained so it must not be making any objectionable noise) I have tracked a 1.2 mpg increase on two long trips now.

I was pleasantly surprised by how easy it was to install. It does whistle when you step on the throttle but I do feel more response when I hit the gas. To me it kinda sounds a bit like a turbo. Overall, I think it's worth the money. Keep in mind I also have the AFE cold air intake to go with it. I haven't seen a difference in the MPG's but it's only been on my truck for about a week.

This thing doesn't do anything but whistle. Spend your money on a cold air intake or intake manifold spacer if you want a bit of extra torque and horsepower. I put on the cold air first so I know for a fact that if where the power came from. Absolutely no change after installing this expensive paperweight.
