Should I go with the Racing cats with muffler bypass or the full exhaust upgrade? What are the disadvantages and advantages of both?

You do not want to do muffler bypasses if you enjoy your hearing.  It is extremely loud, and doesn't even sound all that great.  I would do a Fabspeed moderate generation 3 muffler with sport cats.  A nice compromise, no drone (like the old gen 2 fabspeed), and a nice deep sound to it.

Doc, I am currently running a Greddy Titanium Exhaust on my EVO9 without the siliencer. Will the racing cats be much louder? As I am unable to pass by Fabspeed and am visiting Evolution Motorsports, do you recommend the Milltek exhaust?

I have used milltek exhausts in the past, and they are a good quality exhaust, but more money than the fabspeed.  I would rate the sound level as very similar to maybe a hair quieter.  I know Todd doesn't sell much Fabspeed stuff anymore to my knowledge, so he pushes the milltek stuff. 

Racing cats on a muffler system aren't going to be that much louder.  Racing cats with straight pipes (no muffler), will be very loud.
