So I went out for a test run to better hear the sound. To better describe the sound, if i drive conservatively the sound does not happen but rather when I push the car somewhat ie: no particular RPM range. It happens when moving, and literally sounds more like the sound compressed air makes. as I get higher into the RPM range (>6.5k) the sounds goes away. 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?
