catch can ?
I wouldn't say a must, but after I took apart my motor for the first time and saw oil everywhere coated inside the intake manifold, that is when I started running a catch can system.
All cans have draw backs, some are better than others, some sealed up prevent from 100% clean up/verification, so none are perfect, but good one will do a better job!
My Elite was used, came with a good price, I have modified internal heavily, among "other" things externally to help blow by condensation!
OP, if you are into performance, then, do you want to introduce oil into your combustion chamber?

My recommendation is a Saikou Michi dual catch can (for NA applications). Have only heard good things about them, ever. I'll be going with a Saikou Michi brand catch can when I install my Procharger: http://www.saikoumichi.com/Stage1_LS1_page.html
Right now I have a ghetto rigged setup of two Kobalt (Lowes) brand Air/Water Separators. One for the PCV system to intake manifold, and one for the valve cover to throttle body. The filters they come with aren't adequate for oil, and are known to break down in contact with synthetic oil, so I replaced the filter element with a piece of same-dimension copper tubing I had laying around by drilling a ton of holes in it. Sealed the drain valve with a nut/bolt and RTV. I used copper non-tear scrubbing pads from a retail store to act as an oil catch element (something for the oil to stick to in the bottom of the can). Then built a bracket using a spare network switch rack bracket, GM metric engine bolts, and metal strap. Ghetto, but cost was minimal since I had most of it laying around, and it actually catches oil without creating any risk to the motor. I still recommend a real dual catch can setup (eBay doesn't count as real).

Verdad Gallardo ^^^Their cans are sealed, so verification on built is impossible! I don't know how true that is, rumors is their new can has filters before outlet that lead back to intake. Common sense tells me that oil soaked filter before outlet can not be a good thing!
Go Corvette Forum, search for post by "The Bat Car". He did extensive write up with sectioned various brand cans for show and tell. Very detail!!
This is part of what I did to the Elite internal, machined thin walled T6 extension, extended distance to 3 1/2" between inlet and outlet from the original 1" to avoid quick suck back and providing more surface area to enhance condensation; attached to original inlet filter housing with four 4-40 cres socket head screws. Machined three 1/8" wide anti creep up grooves on reservoir wall to slow down oil creep back:
My clean up and visual is easy and 100% verifiable!

Here is a better view to my catch can external performance enhancements (click on picture then zoom in for enhanced clarity):
Heat sink/radiator fitting (with internal bored to provide additional chamber to capture condensated blow bys) was machined out of T6, attached to inlet cres fitting, fins installed on exterior of catch can to help additional heat radiation and the all important milled G-10 stand off (with two titanium spreader washers to spread clamping load within the milled cavity) to isolate catch can from direct engine heat contact, although catch can is mounted 6" away with the custom T6 extension arm, but the arm is mounted directly to the passenger's head, non the less!
So there is more to catch the eyes with something seemingly as simple as a catch can!
Another hint: look at my oem valve covers and where the oem coils are mounted!!
Mods never stop!!

A few years ago with 40k miles on the car, my 02 had oil traces on the plugs when I changed them out... SO, you can imagine what inside could look like that should been oily, like them runners of you intake manifold.
