Ryan, you've got the right idea, but not quite. The uppipe cat's what you have to worry about breaking apart and getting sucked into the turbo.
To the OP. Find out what they do for emissions testing and then you can make your exhaust decision then. If they do visual and all of that jazz, you're hit with anything other than stock. Save your stock exhaust for this purpose.
If they just do OBDII, make sure that you either A) put the stock exhaust back on and reset the ECU before testing. Or, B) Make sure that you have a cel fix if you try to run the aftermarket exhaust. Make sure that you don't have any cel's.
My car is well, it's like 10 lbs of shit in a 5 lb bag...
