You're catless now. Smelly exhaust is totally normal. The gases/vapors that stink are what the cats clean up.

Is it really white smoke? Or slightly blue-y.

Dunno the conditions of your smoking, but good read:

Lulz well you have removed every single catalytic converter from your car...so no, that is not at all unusual. The exhaust gasses are leaving your motor, traveling down some metal, and exiting the muffler. Smoky, smelly, noxious stuff. With ethanol it smells nicer at least.

If you are really smoking under NA state/vac, it's probably a result of failing turbo seals. The internal PCV system sucks as well. I'd recommend Rob's valve on every N54, stock to 700WHP.

The smoke is normal when deleting cats as long as its not a chimney your car is fine and its likely condensation burn off.

+1 on a video

I'm debating on my mid pipes and we have the exact same dp + berk setup

smell normal.

not familiar with your parts, however they can have a thin film of something (or you introduced it during installation) which burns off after a few days. give it a week or so, or go for a long drive and see if it reduces before digging too deep into possible issues.
