You can avoid this problem by overwriting the exportin buttons and export options.
Example: http://jsfiddle.net/HvHVU/
Function:
function exportActualChart() { this.exportChart({}, { title: { text: this.title.text }, subtitle: { text: this.subtitle.text } }); }
Chart Options
exporting: { buttons: { exportButton: { menuItems: [{ text: 'Standard export', onclick: function () { this.exportChart(); } }, { text: 'With new title', onclick: exportActualChart }, null, null] } } }
