what do you guys think

Which gaskets blew, collector or at the head? I've personally never seen or used hangers any further ahead than at the mufflers. Is it possible your motor mount rubbers are wore out and the extra movement of the motor is stressing the seal at the collector? That the best guess I can give, I'm no exhaust expert either. That, or the collector bolts were never tightened down enough to begin with. Good luck.
