I was just looking at the pic of the components and noticed that the cat is a one tube in one tube out cat. I think you should use a two input one output cat that way you don't have to create a y pipe. The drivers side bank drops down into one input and the passenger side drops down into the other. I can tell you because i went from a y pipe to the two input cat that it's much less restrictive, the two sides are coming together in an expansion chamber rather than welding two pipes together which even if done well leaves them both being cut down quite a bit right before they turn into the one big pipe.

Our first Claret Svx, we kept with the dual inlet single
outlet, ....results where okay.
My second car I consulted with the manufacturer Carround
about which way to go. Their engineer suggested the
single inlet oval cat with a Ypipe for better flow, and it even
works out to a lower cost.....
End result: car did feel like it had more hp then my other car, and my mpg went up even more then my last car too.
Final anaylsis.....this was truly a better set up overall.
