I realize you want rpm but isn't that prop a bit small? What's your goal? Speed?
The cheapest way to good power with the FX is to get a GMS/Tower 47/46 muffler. This will give you nearly the same RPMs as a tuned pipe with none of the fiddly tuning issues. You should be able to get about 14.5K with an APC 10X6 on the ground. Then I would try an APC 9X8. Keep the nitro at 15% or less unless you add another head gasket or two.
