Focus SVT noise when accelerating

[Jon Steeves]

I have recently purchased a 2002 Focus SVT. I have a noise when I am accelerating in mainly 1st, 2nd, and 3rd gear. Does anyone have an idea what it could be? Please click link for sound. Ignore the video part as I had to attach something to the audio. Thanks,
Jon

I checked the shield over the cat and it is secure.
