Thanks man, but it's actually kind of dirty right now.
Greddy pipes don't come polished, so I wet sanded and polished everything by hand. It was a painful experience, and the most painful thing is the dirt and water specs that seem to stick to the aluminum like a magnet. I've searched high and low for a spray on product to just clean the aluminum and not actually polish it and can't find anything. I tried Eagle 1 Nevr Dull and it actually scratched the surface because it's more abrasive than the Mother's Billet I finished it off with. Someone mentioned a product they saw on a truck show, but it's like $150 or something ridiculous. I tried rubbing alcohol and it dulled the surface. There's got to be something. Anyway, sorry to get off topic!
Stock turbo cars come with pcv valves, not just cars with aftermarket kits. I've weighed the pros and cons of keeping the pcv valve and read page after page of information and misinformation. As you already know, when you're under boost, the pcv valve is closed, but when you shift or let off the gas it opens. When under boost, any excess pressure should be relieved through the valve cover breather, but it's important to have a vacuum source here as well if you're running closed loop. Notice the clear braided hose in my picture running from the valve cover to the intake before the turbo, which creates vacuum.
Some claim that retaining the pcv system will promote better ring sealing, but I'm certainly no expert so I can't verify this. Many people simply eliminate the pcv system and run 2 hoses underneath the car and have no problems. Not very environmentally friendly, but the main purpose of this and the Endyn setup is that there's less chance of detonation.
Although inspections only come once a year, keeping the pcv system fairly stock is one less thing to worry about. I just got done putting my catalytic converter back on. The oxygen sensor was seized in the downpipe and I wouldn't be surprised if the person who made the downpipe actually welded it in there. I tried that stuff to free rusty bolts, propane, everything! I finally gave up at 5am, got on the internet to find a cheap replacement, went to bed at 7am, woke up at 10am to find a parts store with an oxygen sensor in stock. The replacement oxygen sensor I bought wouldn't go in because threads of metal from the stock oxygen sensor were stuck in the downpipe, which cost me an extra trip to the hardware store for a tap.
Next year in Pennsylvania, certain counties will no longer just put a sniffer in your exhaust to test your emissions. They'll plug into an OBD2 port. I have an OBD1 ecu with a programmable standalone system and larger injectors which goes in soon to be dyno tuned. This means, next year I'll have to change my injectors, ECU and converter before I can get my car inspected. It's a pain in the arse if you don't have a garage and live in an apartment. Modifying your only car is a stupid thing to do!

Do you just have both your catchcans hooked up to the airfilter pipe going into the turbo inlet?
Forgot to answer this question. Sorry about the long post! No, the clear braided hose goes from the valve cover to the catch can and then the intake before the turbo. The black fuel injection hose (won't collapse under high vacuum) goes from the pcv to the other catch can and then to the intake manifold.
