I see a lot of companies offering catch cans but I was wondering what does everyone recommend? I am not looking for a vented can. i plan on keeping the OEM LS3 routing.

Did you have to seal the drain fitting on the bottom of yours? I know some models open the drain under vacuum.

Ya, the bottom is now totally sealed off

My vote goes to the Mighty Mouse catch can.

I’ve only seen the Mighty Mouse with the vent on it. I am looking for one that’s without the vent.

If you don't want a vent, go with a Norris Motorsports. I believe they're sold under different names as well.

Just know the Mighty Mouse only vents when it actually NEEDS to. There's a "check-rubber" so to speak between the body of the can and the vent on top.
Mighty Mouse is the best out there, in my humble opinion.
