Who's running a catch can?

Guess that experience from 350Z or any predecessor engine will help. Is catch can really so important for our cars which don't have direct fuel injection?

Carbonization is really painful on AUDI engines with FSI (Fuel Straight Injection) , or TFSI (Turbo FSI). My old 2.0T FSI with 82 000 km's on the clock didn't have any issues. But on other hand, there is owners in US which experienced problems after 1000 miles! Even RS4 are really sensitive and catch can should be factory fitted, due to liquid which looks like mud in catch can cas

BTW: Due to no big fuel quality difference and huge price mine 2nd hand TT used 95 RON fuel instead factory recommended 98 RON

It's just another one of those minor optimizations. I doubt it's "really important" for anyone unless you're running FI and/or a very aggressive tune that's more octane/knock-sensitive than stock.

The vapors condense to some nasty greasy stuff for us, but at the rate of 1 tbsp per 500 mi mixed into your intake air, it's not a *huge* amount. It will contribute to carbon/sludge buildup over the very long term though, and it will effectively very slightly reduce your fuel octane rating.
