O2 Readiness - Catless Downpipes

Hello,
Has anybody with Catless downpipes are able to pass inspection by getting the O2 sensors ready, for inspection?

I have z4 35I with MHD, and Catless Downpipes.

I have tried.

Drive cycle - 3 min idle , 3 min 20-30 mph, 15-20min @ 55-60mph - didnt work
VRSF - DP fix - didnt work

What have other people done to get this to become ready for inspection?

Am I doing the drive cycle wrong for this car? if so, can someone tell me the details on how to do it?

Anyone tried to use a O2 Fouler

I'm going through the same, I need catalyst complete. I've had it completed before so I know it can be done with proper driving. Luckily in NY we are allowed 1 incomplete test to pass.
