Wonder if it was because you wrapped it?

Just junk chinesium flex pipes. Good chance that piece killed the first turbo. He's lucky a second chunk didn't come off and get the new one.

Apparently you're not supposed to wrap or coat the pipe before the flex, as it causes the heat to concentrate in the flex. But the breakage was at the far end of the flex from the flange.

I'll also note that I didn't have to put tension on the flex pipe to attach the manifold to the headers. That can also cause premature failure. Might want to look into that, JLarson...
