Another, what's that noise? Buzz/Chatter when under power (Video)

Hi guys, cam belt, aux belt, dephaser, water pump etc all changed about 3k ago now, but recently there's been a strange chatter or buzz when under acceleration.

Car sounds completely fine (to my ears) when idling, revving standing still and coasting with the clutch engaged or not.

As soon as I'm moving and I put my foot down on the accelerator this noise appears.

Video is a bit quiet but crank up the volume and you'll hear the noise when ever I accelerate:



Any ideas?

Exhaust blowing?

yea sorry about that, it's faint alright on the video but in the cabin it's 100% noticable but it certainty wasn't there a while back. It sounds like noisy tappets.

Maybe it is the exhaust, I never thought of that actually. IT's not affecting engine performance or mpg, in fact it seems better than ever since the cam belt change etc.
