This noise is more noticeable on acceleration because the engine is working harder, making the noise louder. With an exhaust leak, the muffling of the noise is cut short, making the noise louder.

Many describe this as an airplane noise, but others might say it is like driving over a rumble strip on the side of the highway or the whirring of a helicopter propeller.
