Hissing by rear tires.
Hissing by rear tires.
I am getting this hissing noise by my rear tires, at first I thought it was the tires, but it only happens when the car is on, it's very weird. I just had Tein Flex with EDFC installed.

I don't think it's the Warlboro. Look under the left side of your bumper. You'll see a big black box with hoses goin into it. That's where the noise is coming from. Something to do with emissions.
