That will be your secondary air injection (SAI) pump.  Only used during cold-start, and not essential even then.  Do a search for the above terms and you'll find a wealth of solutions for getting rid of the noise.  :y

As said .. SAI ... pull the fuse for it... F49 according to Haynes

Fuse 29b in this diagram (I think :)  )
