That's not the maximum pressure it can reach. You were at 7psi with the restriction of the stock cats. You added the parts to run higher boost, but then removed the cats for test pipes. 7+2-2=7
Boost is not flow. Boost is pressure. Removing restrictions will lower boost, but increase flow. Did you dyno the car before/after the switch to test pipes? What you lost in boost may not lead to a 1:1 loss in power, especially with the increase in VE from the engine not straining to push air through the cats. .
