RWD G35 exhaust fitment on AWD G35X

[trioptimum]

I'm wondering if the 05/06 G35X exhaust is interchangeable with the RWD exhaust from the axle back? Specifically, I'm looking at an HKS axle-back exhaust, and I can't find out if it will fit the AWD G35X (without changing the midpipes for the time being).

Could I just throw in a midpipe from a coupe at a later time, or does it require modification? How much will that run me, if it does?

Thanks in advance!
