I did mine same time as installing K&N, so I'm not sure where all the gain came from, but it got louder (didn't like at first, used to it after a couple of days), and much better acceleration, esp. at the upper end, along with 1-2 mpg.

This is the version of the mod that i did too, still no K&N yet, but that is coming. I did notice the bike having more mid-range pull when i did it, but the low end seemed to bog down a bit more, but it seems to have evened out as the computer adjusted.
