Cracked Manifold

Thought i had a gasket blown but turns out to be quiet a large cracked manifold. Explains the smoke in the cabin whilst driving around Phillip Island, thought something had caught on fire. I had thought it was just a gasket and even with the boost turned off i was trying to get as much seat time as i could so i kept going out for a couple of sessions.
Cracked about 3/4 of the way around, surprised it didn't fall off!!!
