It looks like after the pull the exhuast has been permanently bent down. Theories?

That's what it looks like to me.

Maybe the rear subframe/mounts were tweeked.

The force of the exhaust is just that crazy high and the exhuast tips directed the flow of gas such that it exerted and kind of levering action.

I'm with Ben, I can't imagine how much air a 1200 hp motor pushes out at redline, and how much heat the exhaust would make. That with the weight of the turbos pulling down on the exhaust back there, probably bent the mounts down when it heated up.

Well with the turbos being rear mounted the exhaust coming off them would be very short. I could see the heat warping the pipes the first time it was really heated up from the boost.

Looking at the pictures in the opening in slow mo.... They are using V-clamp flanges on all the exhaust connecters. They could allow rotation if not tight. May have been a little loose, since install and fab not finished.

I'm not a fan of these tailpipe turbo setups. Seems like a good way to add a bunch of unnessesary weight, complicated oiling and cooling, waste EGT, and add lag all for arguably easier installation.

I agree that the exhaust just shifted in its clamps under load.
