Without understanding the type and source of the noise, it is not possible to provide any comments.
Is it consistent with engine speed?
Does it occur at a constant rate?
Does it change with abrupt or constant throttle opening?

I have the same problem. It is consistent with the engine speed as well as if I accelerate it in nuetral. Moreover, I have also get it fueled with hi octane, the knocking becomes less but its still there.
