I’m with Overkill here.
In your defense the exhaust appears to be one piece from the cat back.
In the Overkill corner a new factory exhaust isn’t that much, I suspect you’ve already spent that much on parts.
Perhaps you should propose (via certified mail with a copy to the BBB) to Chrysler that you will pay for the factory exhaust if it fixes the vibration and if it doesn’t they pay for it. Be sure to mention that the dealer says they know of a completely stock car doing the same and that the MMWA requires that the manufacturer proves the modification is the cause of the problem before denying coverage.
I feel like we don’t have the whole story here, and that the diagnosis is all over the place.
So, you had the wheels and tires from a similar car that did not vibrate. You put those tires and wheels on the car and the vibration was unchanged, thus eliminating the tires and wheels. (That is a good start).
But then you say:

I swapped rotors with some freshly turned oem rotors and it was ALOT better. I still have a little vibration in the wheel but there is a tab for a vibration on smooth roads at highway speeds in the steering wheel.
So why did we not continue to try to figure out why the rotors changed it?
BTW, did you put the rotor retaining bolts back in?
Then later you say:
Quote:
I swapped the rear trans mount with the stock mount. It did help a little bit.
What? Does it have other non-stock mounts?
What else exactly isn’t stock?
Did anything (Event, modification) precede the vibration.
I suppose If I had access to two Darts and a disinclination to let the warranty handle it - I’d probably borrow the axels one at a time and see if that changed it, after I went back and verified that I had exhausted all options on the two things that seemed to change the vibration up till now (Rotors and trans mount). Also assuming that your fiancé would tolerate this.
One thing I surely wouldn’t be doing is throwing the cheapest possible aftermarket parts at it.
Edit: And even more information comes out while I am typing...
