Whistling while accelerating?

Whistling while accelerating?
Sup y'all...
Whenever I accelerate quickly, maybe half throttle or more, I hear a high pitched whistling noise coming from under the car. It is very loud and obnoxious.
It only occurs when accelerating quickly and it happens in all gears (manual transmission).
I noticed the noise soon after my y-pipe install and right after I changed my gear oil to redline mt-90, though I don't know if either of these things are causing it. I also recently changed my crappy ebay air filter to a k&n filter.
You guys have any ideas as to what this is??
Thanks a lot in advance!

Mine started whistling and it turns out it was a vacuum leak from the hose under the TB.
Check all your hoses and replace them if they are brittle. Especially the PCV valve hose. My PCV hose looked great but fell apart when I was trying to take out the PCV valve to clean it. I replaced the hose and my erratic idle went away. Go figure

he said it was comming form under the car though. get someone to stand near the egine bay or you do and see if it is the intale first. mine intake whilstels but is it not awfully loud.
and i myslef do not hear it that much under full throttle it is just like when i am barly pressing on the petal with my JWT.
it might be but just check before assuming.

Well I have an injen style intake which puts the filter under the front end which would explain why it is coming from under the car. I am now pretty certain that the whistling noise is coming from my intake.
Has anyone ever figured out a way to stop the whistling or will I just have to live with it?

damn, i was just ognna post about this question today. my car makes the same noise, and one my friends riding with me thought the car was turbo'ed. i have the stock intake, just hacked it. would that still cause the little noise? it only does it sometimes, and its kinda annoying.

I wish there was an accordion that fit the frankencar Midpipe...I want to put it back on but those reducers are just too ghetto for me and some flexibility is *really* nice to have.
