Now, with the pipes sitting inside the x pipe (see pic, similar theory), would it create lots of back pressure or turbulence? X pipe sits 6 ft away from the engine. Should it be connected with "step up" pipes to create a smooth transition ( stock pipe goes into a bigger pipe)?

So you're going from a 2 1/4" to a 2 3/8"?
1/8th inch step shouldn't make that big of a difference. In your previous car, you had a 1/4 Inch step. Huge difference, even if it's just 1/8th more.
Assuming that pic you posted is the step in question, and you really wanted to create a smooth transition, you could just get somebody to run a weld bead along the step. Then bevel down the flange to match the 1/8" step for the larger pipe's flange.
