as to the dual into single issue...loose the single pipe. Yes, your car may not need the extra flow capability of a true dual exhaust setup...but----you have twin 3 inch going into a single 3 inch muff with a single 3 inch tailpipe----there will be some drop off in flow.
I suggest a 3 inch x-pipe after the header collectors, and then twin 3 inch muffs and twin 3 inch tailpipes (be careful building this as the passenger side tailpipe will route next to the gas lines and gas tank---be sure to install some sort of heat shield/prevention in these areas).
a total headers/dual 3 inch system will handle anything any modded 928 engine has to offer---even a blown and stroked 928. 
OR......
you could just put a set of sidepipes on it like I did mine----but everyone would give you a bunch of crap about it.

Thx Russ, appreciate the feedback...
I am throwing all kinds of ideas around, sure I will come up with something soon, or go crazy, one or the other...
