New k5 owner hear 👌. Curious is there any catch cans available yet.

I would guess that the current generation cans by Mishimoto and ADD should work... It's all just plumbing, with the only really specific component being the actual mount the can attaches to, so if you need to build that one part yourself, that's not too big of a hurdle.
