It broke? Strewth. Sounds more like it's been securly fixed and prevented from moving about as the engine vibrates.

I seal my headers on with silicone sealant, so they don't move at all at the engine end, just bounce round on the chamber mounts as they need to and haven't had any problems so far. It also stops thje spooge stains inside the fairing.
