While the layouts are slightly different (mine will be less piping and less restrictive while still having a provision for a cat and quiet restrictive muffler), I'm making something similar right now (x-pipe to y-pipe and exit out the center). All piping lengths and crossovers are chosen to amplify the desired frequencies from my tonal analyses.
