The airbox 3" inlet modification will increase the amount of turbo noise. Also changing from a paper filter to a K&N filter will increase the turbo sound somewhat. Although more noticeable, the turbo sound should not be obnoxious.
Adding the Viggen intercooler should make no difference in turbo sound.
Some possible area to look at:
You may have a leak under pressure somewhere in the intercooler connections.
Either the intercooler or one of the intercooler connections is loose or resting directly on the sheet metal and is coupling the turbo sounds to the sheet metal.
The Amsoil or ITG foam panel-type performance air filters will decrease the amount of turbo noise.
