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.

I pass every one of Minnesotas required emissions checks ....





:D

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.

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.

just wondering but how can you not pass with kpro?

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