I have a 01 with 92k miles and everytime i drive, i hear a whistling noise coming from the middle back of the car or if im mistaken then its the middle. Either way its one of those but it doesnt matter what rpm or mph the car is at. It sort of does get louder as you gas it more too. Ive looked it up and I find different answers like clutch bearings or throttle body or something else. I just want to clear it up.

As for the rattling noise, I hear it on the driver side a-pillar whenever I canyon the car. So im under heavy braking from around 50-60 mph with heel-toes and rev matches and high rpms. The noise comes up after a while of doing this if i were to run a couple laps on a canyon. Again I cant find anything on this and someone told me its the transmission/gearbox but i am here to clear this up to. Thanks guys

p.s. I did a tuneup at evasive at 87k miles and the car is completely stock

 

Do you hav an aftermarket intake or remove your airbox? If so then thats why and its normal then.

 

I have stock airbox with a k&n air filter in it and the airbox is gutted, also its missing like 2 clips that hold the top of the airbox together

 

yea that's the same thing as removing the top because it's not seal tight. Try borrowing a local member's airbox and try it out.
