Well then yes, the exhaust system should work on a 1.6L B13. If you are swapping the muffler for another one then you can have that fitted. I don't see any issues with your setup if you do this, but I am not 100% correct. Have you "searched" to see if anyone on the board has the Monza/PS setup on his or her car? If not, I would start there.
Again as for the manifolds, a 1.6L and 2.0L manifold can not be swapped. But a 1.6L manifold from a B13 and a B14... maybe, unfortunately I do not know.
Hope this helps any. Good luck with the project.
