Exhaust sounds True duals vs X-pipe or H-pipe.
None of them sound right ,
The distinctive sound of the Mopars is the "resonator" on the end .

I REMEMBER the soundS of the stock hi performance Mopars, 68--later RR, GTX, Dart, Duster etc
But I think they all had crossovers. The B bodies, anyhow.
I still remember arguing with my 69 getting the gearbox out. The exhaust was all welded, and the "H" pipe kept the pipes "in the way"
The 70 had headers via the original owner, an H pipe and the mufflers "incorrectly" tucked up under the floor, with DAMN-I-WISH-I-HAD a pattern for the side exit pipes They angled outwards soon after the mufflers, angled parallel to the body line about 4-6" inboard of the rocker, wet straight back about a foot? and they angled out 45 in front of the tires with the ends sliced parallel to the body. 2 1/2" pained black. Looked great and sounded bad as hell.
There was a "cross" brace near the rear, and the entire exhaust was therefore one piece. I could drop a hanger off the frame on each side, drop the collectors, and pull the entire assy. out from under the car
