tfs track heat intake

[bigblockcoupe]

i bought a tfs track heat intake from a buddy he wanted to sell it because after 200 miles he was tired of a whining sound it makes almost like a vacuum leak i thought maybe it was just a gasket or something anyways i put it on my car and it still makes that same annoying whistle i have changed the upper and lower gaskets 3 times to no avail and i guarantee this thing isn't leaking around any gaskets i tried the old carbuerator cleaner trick and after 2 cans i can't find any leaks anywhere it makes a high pitched whistle at idle and a momentery little whistling noise when you throttle into it it performs fine it's just annoying has anyone else had this same problem? i'm wondering if it is the way the runners are shaped inside the intake?
