will catted downpipes smoke?

My MRT catted turboback smoked like mad.

It hasnt been warm enough for me to notice the smoke with the COBB stuff. I know it will come back though, so I'll have the PCV TSB done soon enough.

It took over 6 months before I noticed any smoke from my catless DP. Every once in a while I get a smoke show, but it passes. Long periods of idling will lead to it. It sucks.

Supposedly the updated Pcv fixes the problem
