I like your adapters. I don't think they are wrong but I am thinking that the mufflers have to move with the engine movement otherwise the weld on the collector flanges will eventually fatigue and crack.

Note that the engine and ZF are joined together with a whole bunch of bolts and will move together as one unit. If they're moving independent of one another or in different planes, then you have a whole lot worse problems than the risk of the exhaust flange cracking. Therefore, the collector flanges should not fatigue and crack since the exhaust, engine, and ZF are all joined together and move together, as one unit.

I understand that. It's just that the mufflers are hung way out there like diving boards and vibrate quite a bit. So much that they loosen the header bolts near the firewall.
