Exhaust coming loose

Does anyone have a similar problem? Ever since going K04 my exhaust has a tendency to slide loose during hard acceleration. When this happens, I can see the exhaust tips have shifted out further than before by about 1/2" to 1".

I have re-tightened the clamps many times. Have not looked at the exhaust recently, but I believe that it's all coming loose at the bracket with the rubber bushings towards the back of the subframe.

The steel rods/hangers from the stock downpipe have mushroom heads to retain them in the rubber bushings, but the steel rods on my downpipe does not. I also believe this is putting stress on the flex joint on the downpipe.

Whenever it slides loose, it will begin to rattle and be more prone to what sounds like backfires.

I've got the AWE. The CAT itself is fine - already pulled it out and the rattling is not coming from there.

Is this a common problem? I wonder if I can ziptie the hangers to the subframe bracket and call it a day.
