I also have a stock exhaust system from an '87 930, which fits reasonably close to the OBX stuff.
This is backwards. The OBX stuff should fit reasonably close to stock. If it doesn't then nothing will line up right or fit.

You need a bigger waste gate, especially in a low boost application. Stock replacement for the 930 is 46mm. You will need to vent more exhaust to sustain 0.5 bar than higher typical 930 levels.
