Hey guys im looking to get a new intake, was looking at the Alta intake set up, basically i want a CAI set up that will let me hear the "pssssttt" sound when my turbo is going off, but the Alta is fairly expensive anyone know of a cheaper way to get these results? i would imagine removing my air box and putting a bigger air filter on it would do something like that but i dont want to go tinkering around without knowing. any feedback would be much appreciated.

Thank You
