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.

The pipe is 2.5", then at the X its 3 1/2" wide by 2.5" tall in an oval shape. So, its about 7.5 sq in area vs a 2.5" pipe of 4.9 sq in. Theoretically, there shouldn't even be exhaust pulses hitting the X at the same time, so chances are it's not really restricting anything. Most X pipes I've seen are a bit smaller than 2 pipe diameters at the X.

I would imagine that this would actually help the scavenging effect, which is why you use an X pipe to begin with.

I have mufflers that resemble the AAR cuda mufflers (they are Dynomax Super Turbo), so the entire exhaust will drop off as one big piece if you have to do any work on the transmission.
