340 3" exhaust unbearable

The hangers are rubber strap w/ fabric weave in the layers. U bolted behind the mufflers and then again at the tail pipes near the bumper. I'm going to drop the whole system and let it hang mostly by the collectors tonight and see. It has about 1/4 clearance below the body all along. Engine shake may twist it up into the body is my last resort.

If my crossover and cutouts aren't postioned wrong then it has to be a mechanical interference that I can't see.
