Is my meoooow knackered (CAT)

Since fitting my Orb the noise has been fantastic - had a little issue with fitting etc....blowing for the joint at the cat. Just recently though I have noticed that when the revs get to around 4-5k there is a noise like it was blowing again, I checked it and nothing was blowing. The noise sounds like a metal ting noise. You can only hear it when you put your foot down???

*Also to add* when I was under the car listening to see where/if the blowing was coming from it sounded like it was coming from more up the manifold - but you can't hear it from the top side.

bit of an update tonight - I parked up and gave the car a few revs, when the revs were higher and you backed off it sounded like something was loose? like a metal vibration. But nothing is loose - I am thinking of trying a decat to see if the cat is the cause. bit cheaper lol

It could be a shield around the exhaust? I thinkI have the same problem y'know, my cat is also gone to as engine management light confirms this.
