X & H pipe vs straight dual exhaust

I thought a lot of Mopars came from the factory with H-pipes. It increased low end torque. The factory wouldn't of added it if it didn't do something.

I think there is a lot of opinions on H vs X pipe if one makes more power than the other. Since the location in the exhaust system matters and it could of been placed in the wrong location and therefore wouldn't feel any difference in power. From what I understand is that an H-pipe should be placed right behind the header collector. An X-pipe should be about half between the header collector and the exhaust tip.



That setup is going to be restrictive. The exhaust is only going to flow as much as the most restrictive area. There are 2, what looks to be 3" pipe, merging into the X-pipe that is only the diameter of 1 pipe at the middle of the X.
