I've had mine installed for about 3 months now. I can honestly say i didn't notice anything, but maybe a bit more of a sound. I also have a Gintani race rear section and Challenge street x-pipe. Would i do it again, probably so, since it wasn't that much ~$440. Also, cause i saw where kitw reported 6whp with it. I also have the dry filter.
