Unusual sound

[Performance nut]

My car is completely NA and mostly stock (just headers). Yet somehow when I'm fully on the throttle, it sounds like I have a BOV when I shift. Best way I can describe it, it sounds like a whooshing sound you hear on turbos.

My car does that too. It's a PP with Ford performance Touring exhaust & a K & N, nothing else.

Mine does this as well. Manual 3.55. I just thought that was the intake sound tube. Does sound like air is being released. Only when I put my foot in it. Happening for the past 5 months. Stock other than axle backs.
