Anyone able to pass emissions test with headers and all cats deleted?
I thought I had another year before testing, but I got the letter last week.
I have headers with both primary and secondary cats deleted. I live in Illinois so I don't believe there is a visual inspection.
I have a Eurocharged tune so I don't get any CEL's, but I'm not sure how it affects the o2 sensors or readiness monitors.
One suggestion I got was to look into mini cats, but I am clueless on what that will do, if anything, to pass emissions.
Anyone else come across this situation?

You need to ask you local smog shop how many monitor not ready can they pass u with by state law?
Pa and ny if you car is from 96-2000. U can have 2 not ready and pass inspection but from 2001 on u can only pass if u have 1 not ready .

I'll prob stop by one this week to ask.
Maybe the dealer can check readiness monitors for me to, if they have the tools.
Have you had to perform yours yet? You are catless too, right?

If you have not had a check engine light nor have done a reset, and have driven a normal week of driving your readiness monitors are fine.
As for cat delete and mods, it depends on the state and the thoroughness of the inspection station.

If you have issue just tell your tuner what your issue is and they will send you new file so u can pass smog.

Fortunately I don't have to worry about smog check.
The EPA site for IL states "Vehicles will fail the OBD test if the MIL is commanded to be illuminated and diagnostic codes are present."
I'll have to see if any codes are present.

If your check engine is on, you have codes.
If you clear codes you have to drive a few days to reset the readiness monitor.

I hear that they will pass the sniffer test. I do know of someone with same setup that didn't pass OBDII emissions. No CEL. I think the readiness monitors are off. I'm still waiting for an individual with LTs and CATS to go through a OBDII test to see if it will pass. Don't bother PM'ing me for their names. Not trying to be a d*ck but I think they rather remain anonymous.

In California it's very strict. In order to pass a smog check, all monitors with the exception of one need to be set. We are looking forward to the elimination of the tailpipe test for vehicles 2000 and newer. Testing will be a lot faster and hopefully cheaper when this procedure goes into effect.

SO glad I don't have to do this. My $12.50 WV inspection consists of mostly checking lights, horn, brakes, tires, and a look-see under the hood/car. If the car is new or has less than like 10k I get basically a pass. My inspection station is also my tire dealer so I get a lot of leeway. My MB dealer also inspects for "free", but are a bit more strict. You have to have a valid WV registration to get inspected here so no out of staters.
If these tests are soley computer/OBD-II based is it possible to put somekind of device that cheats and gives the correct answers? I'm thinking somekind of dongle on the OBD port or some software code that cheats. There would be $$ deveoping this.

You would need to load the VIN into your "ODB Cheat" device.
The other thing is you would need to be ready for whatever request the service machine makes. Not hard, but would take some snooping.

I had my first mustang (01 vert) pass in IL with stock mannies but no cats. I tested at the facility right off Elgin/Ohare. There was no visual and being that the tires were low pro's they wouldn't even put it on the rollers. They just stuck the wand into the passenger's side exhaust pipe for about a minute and sent me on my way. The ECU tune took care of the 02's. Id give it a shot if I were you.

i've got a eurocharged tune and catless headers as well. from my experience, the o2 monitors are turned off with the tune. i tried to request once to have it turned back on but even after the retune, they never became ready.
my state only allows 1 not ready.
i have 2 in not ready status. o2 sensor and o2 heater... i've been wanting to play with a few options such as extenders but haven't been able to really try since i don't believe my o2 sensors are turned back on. i would think if they were on then i would be getting a CEL.

If what you're saying is true, then the o2 sensors control all the tests ...
If you're referring to the actual sensors in the ECU, then are you saying that there isn't a separate "switch" to turn on/off the o2 sensors... are you saying it's 1 switch for all the sensors?

This site still says 2 not ready fails
https://www.txdps.state.tx.us/rsd/vi.../ready_not.htm
Could you pm me where you got it done?

I could be wrong but that doesn't seem right... each part has its own test... if a particular test fails, then that monitor will be not ready...

"Not Ready" means that even though the system is not showing an error, the car has not been through a long enough run cycle or enough warm up cycles for the "good" condition to be considered valid.

As far as the o2 sensors go, I was thinking of reverting back to stock a week before and drive it around normally and see if I get lucky with the test. There is no visual inspection and no sniffer.

after ignoring the ready status of the monitors for a long time now... i went and checked on them today...
all of them are in READY status except 2.
the 2 don't say "NOT READY" next to them...
instead they just say "NO"
Oxygen (O2) Sensor - NO
Oxygen Sensor Heater- NO
