DIY: Passing Inspection with a Gutted Cat

If feel like a cat on a rotary is not worth it. For the amount of damage it can do to the engine I much rather take the risk of riding around with it gutted. Here most place just check insurance and registration then slap a new sticker on.
If I HAD to have a cat for inspection, I would go buy that cheap bolt-on autozone cat and use it once a year for inspection. Swapping the mid pipe on this car is pretty quick and easy.

The N/A's were just what I thought, meaningless. Now the real emissions tests the car does you can only have 1 of the 8 set as incomplete. Passed the other day easily with the cat off the car by just using a cheap code reader to see when it was ready. The test really should be harder to pass than that.

Avoid operating the car at the load/rpm points marked by a one in the attached image.
Rear O2 DTCs are set in that range.
Disseminate this information widely so that all states will be forced to implement better testing.

DTC masking does not affect the readiness monitors, so it is possible to fail a plug in test with a Cobb. However, most states allow a car to have some number of unset readiness monitors.

Masking prevents the lookup of the DTC identifier after a problem is detected.
The other routines associated with that DTC still run - misfire handling, readiness monitors, and other stuff I don't understand at all. So the ecu still responds to the error, it just doesn't report it.

I cleared the cel I had (p0420) and then drove until 7 of 8 emissions tests were completed by the car which took a few days. The only test that would not complete was for an o2 sensor. Its been 70+ miles since I deleted that code and I still have no cel.

I don't have the test here were I live but it is funny that a person who care about the enviroment would drive a car that not only burn gas but it also burn oil and have the back bone to coment!! About it
I ably ask about this because I may not have the choice at this time are the money to get a new one so to ovoid damage to my engine what do u sogest.
I would clean it if I think paint thinner should work, but then again more palutant

I was about to look for this thread and post, glad someone beat me to it. First Jamcan I under the first part of your post but you lost me on the second half there.
I am now 300+ miles after I reset my cel and it is STILL trying to decide if my oxygen sensor is good or not lol. Still no cel for me but I know its coming. So you really do not have to rush and get emissions done in those first 20-30 miles every reset.

Sooo was mostly reading this thread for all the lols it was worth, when I saw the bolt on extension for the 02 sonsor....
Soo my dealership tried this for me oddly enough, and it was a no go as a fyi.... 02 sensor was still unhappy.
When I had it up for sale a while back, I simply stated it had a high flow cat, and wouldn't pass emissions.... Although here it isn't a state law, it's county. I could sell it to someone a couple miles north and emissions wouldn't be required

Sauer you are dealing with federal law here, not so much state or even county. Yes the state may say in that certain area no emissions test is required, but it is still federally unlawful to remove the cat from the car in the first place.
Your dealership installed something that was meant to circumvent an emissions test? They must have some smart people working there.

While working at a dodge dealer, I had the unpleasant opportunity to work with an srt4, the ecu was flash so that the monitors : o2 monitor, o2 heater, and catalyst, went to N/A. So the ecu would be ready for inspection almost within minutes of idling. Now I know we can mask dtc's ( cel or mil) with the AP as I have done but can we mask the readiness monitors like this srt4 had?
