Default Anyone passed emissions with aftermarket cat?

Just a question for you guys. Has anyone been able to pass emissions (really I should say get the readiness monitors to set) with an aftermarket cat and flashpro/kpro? I'm just curious if there are limitations in this regard. It looks like people are able to get it to pass with SC's, bigger injectors, etc. but I wasn't sure if that was running the oem cat or aftermarket.

Yes I pass both OBD and sniffer test with kpro and Berk HFC, it does need to get really hot to get the emission values down enough though.

I have passed in CA with a 63.5mm Ballade Sports HFC. The readiness codes will set to 'fail' in the winter, but luckily I always end up having to smog in the summer when the codes easily set to 'pass'. FWIW: my regular driving will keep the readiness codes 'not ready', and I have to drive in stop & go traffic for about 5 miles before they will set to pass/fail.

Passed several times in Ohio. Self service Kiosk via OBD2 port, no visual inspection or tailpipe sniff. Berk 63mm High Flow Cat.

My Berk 63mm HFC is fine with an O2 extender, not sure if they do tail pipe sniff in MA but it passes inspection just fine.

AZ won't pass with Kpro. I assume flashpro would not pass as well.
They just do an obd2 check. I passed with a 70mm test pipe with factory ecu.

I pass AZ (ODBII) emissions with a Berk HFC and Flashpro. I know there is an option with Flashpro to disable secondary O2 which would almost certainly cause a failure. I have never had to use that feature, no issues with CEL or readiness monitors in 5 years.

AZ specific, it used to pass but recent testing is more stringent. Some details here:
