Recently I installed this item. Right off the bat, the sound is awesome. I have noticed slight gains in acceleration, but nothing too crazy. There has definitely been a drop in mpg, even while driving like a granny. I have also noticed that the gears don't automatically shift as smoothly. I'll most likely be upgrading the exhaust and then reprogramming the cpu to accommodate.
