It is not associated with any particular gear but Ive notice it happen from 3rd and up. It does not happen under load. I do have an Afe filter which possibly could explain the sound?
If the car is parked and I rev the engine high the sound does not happen.
A question for anyone!. If you were to have an exhaust leak would it usally be heard through all RPM ranges and at all speeds? Iam assuming that it would be heard if reving the engine while parked and not just while driving?

An exhaust leak is usually not a hissing sound. Usually when you have an exhaust leak you know it.
Maybe you can record a sound clip or video? My car w/ full Akra doesn't make any hissing sounds. Just roaring on a rampage sounds
