Hard launches knocking H-pipe loose

Hi: As I've posted before, the car is new to me and I love it (2013 GT500). It has Magnaflow exhaust with an offload H-pipe. When I launch hard, trying to do some burn outs, I have experienced a separation of the H pipe/exhaust pipe (I'm not a mechanic, so to clarify, it's the junction that sits at about the transmission). The first time it was only the passenger's side. This time it was both. The car is wearing MT Street II on the rear.

I have tightened everything up by cranking down the nuts at the junction (2 nuts on each pipe). It was fairly easy to push the tail pipe forward by pushing the tail pipes forward from the rear. Any ideas? Normal?

FYI, it does have Eibach springs, and the BMR adjustable pan hard bar and rear suspension parts which were placed by the previous owner.

Thanks for your replies.
Brian

I am not sure....it was installed by the previous owner.

Take a look and see, if it's the MRT H pipe than I have seen those ones separate in half were they connect, you may need to have someone weld it.
