Are catch cans necessary with single turbo setups?

Which catch cans come baffled? A quick google search yields no results of baffled cans, only unbaffled cans such as the Greddy etc. Do you have a pic your catch can setup lexforlife? Btw, I met you when I was in Miami with moosejaw aka Andew. 
You have a nice SC for sure.

hard to explain put has to do with the speed of the air being pulled by intake side of turbo and how much actually gets vented .. ill see if i can find the article online from the drag racing world that lead me to this design.. even my tuner liked it alot and saw engine was more responsive since doing it

I ran my setup without one, and ended up blowing out my front rear and cam seals. a simple $20, yes $20 setup fixxed that. Now I'm about to put my whole setup back in after I have pulled the motor, cleaned and replaced all the seals, etc.
Just do the catch can, it's worth it.

I pull 19-20in at idle with stock cams just FYI. Most aftermarket cams pull less due to overlap obviously, but I wonder if having no PCV through the intake has anything to do with the higher vacuum numbers. Since PCV is a controlled vacuum leak, maybe having no accommodation for it leads to more vacuum? Oh, and degreeing the cams can get rid of the overlap and bring vacuum numbers right back up as well.
