sounds like a blow off valve

well first of all. sorry guys but no this is not a thread about me having or getting a turbo. since i know thats what you thought. haha

when driving my car though when i step on the gas there is a sounds that the car makes. i dont really know how to describe it other than it sounds like a quiet blow off valve. but its not short like a blowoff valve. sometimes it does it for 10-15 seconds. it just depends on what rpm range i am in i think. its not a whistle from a vac leak. but other than that i dont know what it is. does this sound familiar to anyone?

here is a list of mods that may be able to get some ideas going for what it could be. (ive been hearing this noise for so long now i cant remember if it started right after the mods)

KnN drop in
samco intake tube
md 5/16 spacer
nismo y pipe
coupe midpipe
