Had one on mine for several years, works great.

Catch Can install question
Most catch cans have a small filter screen on one of the ports, to try to make the oil mist condense on them and filter the liquid spray from the air, and the other port goes directly into the can.
So which port should go where in relation to the crankcase and throttle body ports? Should the side of the catch can with the screen on it go to the throttle body port or the side the goes to the crankcase breather?

These catch cans seem to work pretty well. I have one installed on mine too.
The way I think of the catch can is an inlet and outlet, since you want to filter the air of oil contaminant, the top of the can is the inlet, the side is the outlet.
The goal is to filter the air before it hits the throttle body, so you want to insert the catch can in the line between the crankcase and throttle body - so the crankcase feeds into the top of the catch can and the throttle body connects to the side. By doing so, the oil condenses in the mesh and falls to the bottom of the catch can and air for the throttle body is drawn off the side.

MikeCsix is correct - top of can goes to the manifold, side of can goes to throttle body. Elite has instructions on their website. I installed one recently, very good quality, easy install and it works.

The Elite Engineering Catch Can is actually one of the best cans on the market just so everyone knows. You cannot go wrong with Elite or RX !
Here is a cutaway of our can.

In basic form, Elite is very high quality. With a few additional mod, Elite gets better plus can take apart for 100% cleanup + visual verification.
Here is the unscrew, separated view with a couple of mods:

To me the best can itself is AMW. Have you open one? It's very similar to EE, but it has grooves inside the can, to prevent oil from creeping up the can walls with high vacuum. I bought EE for my previous Vette and GTO. To me, it boils down to their brackets. EE has a better engine bracket. But with the Helmholtz chamber on the GS, AMW has a better bracket where I installed mine (looks OEM). Those 2 are the best cans IMO. The most expensive too, but as you said, you get what you pay for. By the way, EE is too wide for my application.

The supplied mounting bracket from Elite gave me 1/8" clearance from the heater hoses and at a slight tilt once mounted, just too close for comfort. Additionally, to unscrew bottom reservoir, catch can need to be removed from arm due to lack of bottom clearance. Total inconvenience for me!
Consequently, made my own, based on the two intersecting angle on the head and milled cavity on lighten T6 bracket to precisely fit the head corner, milled cavity also assure mounted catch can perpendicularity. Once mounted, I have an inch of clearance from the surrounding heater hoses, inlet/outlet hoses to the catch can elevated/away from direct engine heat contact, elevated catch can is insulated from engine heat/exposed to 360* ambient air and ample clearance at the bottom to unscrew reservoir for cleaning convenience.

I have seen the inside! One thing I have noticed is the outlet location is fairly close to the inlet tube (end contained the mesh) and with no physical baffle to slow down the blow-by other than the anti creep grooves. Inlet end with the mesh is relatively high off the bottom of the reservoir, for a good reason, given the mesh housing/inlet has no bypass, if it is long enough and close to the bottom (which is a good thing in terms of further distance from the outlet) but existing design, mesh might get submerged in captured blow-by, if timely draining is neglected.
On the other hand, Elite mesh housing (way off the bottom) has flange at end (acts as physical baffle barrier) and raising blow-by has to squeeze around the flange into and through the cavity in top housing to escape. That is simple and ingenious. Although the distance between inlet/outlet is short, but a person can simply address that with an extension.
All in all, no one brand is perfect!
Someone else can find flaws with my alterations to the Elite, I am sure.
But that is the fun part, not accepting what is out there and the constant pursuit of making things better.
