No disrespect here but, I don't believe the hand-o-mometer version of the anemometer. I don;t doubt that it's an improvement but, I don't think it's anything huge. It likely feels like considerably more flow because there isn't this cavernous muffler to slow down the flow of the gas before exiting the pipe anymore.

Are you going to do before and after dyno runs?
