Noticeable increase in power, acceleration and MPGs. Installation was fairly easy but for some reason I had extra screw and nuts(?). I used You Tube and written instructions provided. There is a loud drone sound at mid range but quiet when running low RPMs. Best music is climbing steep grade or passing on freeway. I highly recommend.
