Default Harmonic Exhaust Rattle

I'm getting a harmonic rattling noise coming from the Corsa exhaust system when the engine is fully warmed up and only when the engine hits 2000 rpms.
Has there been any issues with the Corsa mufflers?
I've checked all of the exhaust bolts. There all tight.
It's a pretty anoying sound.
Please help.

Jim
