Install only took and hour and a half, that included taking out the old airbox system. I took on of the rubber grommets/screwposts out so the bracket would sit lower. It just sat up to hi with the grommet in place.
You only here the difference and feel it above 2500rpm. Highway cruising and idle the noise isn't any different. This will definitely help when passing on the highways, that is where I seem to need it the most!!!
