I just just custom fab a CAI , with some 2.5" tubing and some couplings as well. As for a Turbo noise if its too quite.. just find a place to install a Blow off Valve , then you get the Turbo purge you guys want!
Did your turbo sound get louder as well as your BOV when doing the CAI? I know my last turbo car got significantly louder just from a CAI. Do you have pictures of it?
