Take it back and tell them to change it. Water/condensation will always form in exhaust systems.

any water would soak into the wadding and dry up when it next gets hot??... eventually that's what rusts the exhaust... but it won't make a noise in there??

It sounds like a baffle plate has come loose. As said above, if it's under warranty insist they change it. What they might try to do, if you're not watching, is hit the box with a hammer to trap the baffle and stop it vibrating. If they change it, it doesn't cost them anything 'cos they will get it replaced by the manufacturer (who they screw into the ground on price in the first place)
