Allow me to help, don't put it on. Had one on two cars already 8 and 10. Thought I was doing right by my car, but more or less it's added junk that doesn't do much or anything at all. Never had any fluid in one that you could drain, the mounting position has to be so perfect to get the oil to condensate and run off. Then, after what I thought was perfecting the setup on my '10, I had some work done down at CBRD and Chad told me he's never seen a street car fail because of oil cokeing the turbo. Just my two cents.

The tricky part with catch cans is using them properly and not creating a leak in the vacuum/pressure system.
for instance, the line going back to the intake for the breather, if you put an inline catch can that has a filter on it, or fittings that leak you are effectively CREATING a vacuum leak.
We've seen them hooked up to the line where the check valve normally is going back to the intake WITHOUT the check valve... and then you basically pressurizing your catch can, and it blows oil out wherever it can.

The only catch cans I've found to be effective are the ones with an internal baffle, that effectively filters the blow by. There is also a how-to on it in the appropriate section if you have time and tools, otherwise, Saikou Michi and Buschur make good ones.
I have the dual catch can set up, and I barely get any fluid from the valve cover --> intake. But get a good amount from the valve cover --> intake manifold. Chad is right, when you hook up the catch can in-between the valve cover --> intake manifold, make sure the one-way valve doesn't pressurize the catch can!
