there was a largish thread on this a while ago (try the search). Considered normal anyway. Mine does it too.

You are probably hearing the wastegate working, if it is then nothing to worry about, all perfectly normal.
A reason that you may hear it more in lower gears could be that there is less road/wind noise at lower speeds, its quite hard to hear with OE airbox and cats, sound proofing etc
