Oval mufflers will be quieter just because of the added volume,
and amount of sound deadning material that can be in the larger area.

If you want less "echo" inside the car, pull the bottom of the back seat up,
and add sound deadner under it, most Mopars are just Metal,
under the rear seat.
Heck even carpet padding will help, I also added carpet padding to the
trunk divider.I forgot to take a picture of the rear where the padding mostly is.
