The stock muffler takes away 12-15HP according to my dyno results on a 300WHP 930 engine.

Julian, your numbers are in line with what I have seen with that setup when going from 0.7bar to 1.0bar boost. The SC cams are good for ~20HP over stock but change the dynamics and torque by much more.

Bill, I would expect your stock engine with headers and K27-7200 to be ~300WHP @ 0.8bar.
