Haha, yes. I've had had it crack there once, and then again after a washer was melted to reinforce the weld. I've also had cracks at the 4-2 merge and at various flanges. I've lost way too much track time with mine and have given up on repairing it. What's the point having great performance if it leaves you stranded?
I've been running the stock header again while deciding what to do next.
