whistling noise

[merlinx]

I have a 99 GST and I installed a LICP and a UICP, K&N filter kit, 1G valve, N1 Apexi cat back, high flow 3" Cat, 2.5" down pipe, and a boost gauge. The car runs great. I can definetly feel the different. My only question is, do any of you get an intermediate whistling sound from the intake in traffic? Also, I noticed when going close to 100 MPH on the freeway I heard this load sound. Im thinking it might be the air rushing into the intake bus is this normal? Any help would be appriciated. thanks

yeah, its your intake...my car has the k@n and you can hear it whistling when it pulls air hard

I just put an air raid system on my jeep as well and at certain throttle positions it whistles as well, almost sounds like it has a turbo
