How much whine is obtained with Stage 2 alone? I am currently looking into purchasing this upgrade for my 05 cobalt ss/sc but was wondering if it increased the whine significantly without the help of a CAI. I eventually will purchase an intake in conjunction with the stage 2 but was just wondering if the sound will hold me over for awhile. Thanks, I also am assuming that the smaller pulley will make the supercharger louder but any previous experience would be appreciated.
