I only had the factory air box for...200 miles, so not sure if it's my ram air intake or not, but mine will always "whine" like a 2psi supercharger. I usually hear it in 4th going about 30-35mph, but I do hear it in all gears. I've always just assumed it was my intake...?

you can read about the hissing sound in your car manual its probably just your lsd you can hear it when you driving slow in high gears like around 3rd to 6th to eliminate the sound drop down a gear and see what happen the sound use to bother me i didnt think it was normal but after reading my manual i come to learn its normal maybe this can help but if the sound is coming from the engine then that could be a leak
