On my 4.0 turbo, i'm using stock manifolds. The passenger side crosses over by the trans and Y-s into the driver side, single pipe up to the front on driver side, to the turbo, then out across the front then back along passenger side. Past the trans, the pipe splits off into duals all the way back out.
I have pics somewhere but not uploaded. This is the standard routing of powerhouse's turbo kit.
