For anyone in the state of New York running a catless downpipe on their 10th gen, I was wondering if you had any trouble passing emissions for your Inspection sticker? I'm aware of the feature in KTuner or Hondata where you can disable the sensor or something and you won't get a CEL. I'm not sure if the inspection machine picks up on it or what. Please tell me if you've been able to pass with the catless downpipe or not.

I don't know about NY, but in California you would never pass smog as they also do a visual inspection. They also have to verify the CAT's EO number

If you’re from NY they usually print out a sheet for your records and give it to you after the inspection stating whether you passed or failed. There should be a reason on that paper as to why you failed. Do you know if you were getting a Safety inspection or Safety & Emissions?

You won't pass unless you know someone. I learned a long time ago and have been going with high flow cats ever since.

Most states check for 2 things when doing OBD scans for emissions:

1. No CEL codes.

2. Emissions readiness monitors are all OK.

Emissions readiness monitors are things like the catalytic converter, evaporative emissions systems, etc. These are separate from CEL codes. They typically read as OK, bad, or N/A. When you use a tune to disable the CEL codes for a downpipe, usually this sets the catalyst readiness monitor to N/A.

Here in Maryland on my last car with a tune that disabled downpipe CEL codes, the catalyst readiness monitor was set to N/A and I still passed. But different states have different rules on how many of your readiness monitors can be N/A or bad before you fail and I don't know the NY rules.

Otherwise if you failed a visual inspection they probably looked under the car, saw the downpipe and said fail.

NY allows one N/A of readiness and 0 CELs for current cars

Source: recently went in for inspection in October - none of my monitors were ready due to a recent flash. Drove on the highway for an hour to have 2/3 monitors ready.

These are:
- Monitor Catalyst
- Monitor EVAP
- Monitor O2

EVAP was the one that remained N/A for me as there's a specific pattern of driving that needs to be achieved for this to be Ready.


Readiness is cleared after the following conditions occur:
- Change / Disconnection of Battery
- Re-flash of ECU

I used to live in NY. It's not what you know it's who you know. Sad but true. I believe that you must have some semblance of a catalitic converter. That is why cattless is sold as off road use only. They sell modified high flow cats that are at best on the edge. Make friends with a garage guy who handles the stickers. Be up front and honest. In the fine print it's actually a federal crime to modify your cars emissions system. Who was it? Volkswagen ... It's quite serious. So ... In California it's a no way ... In NY ... It's a maybe. You need like a Joey Buttefuco type of garage guy ... LOL ... Hey Joooeeeyyy

Here in Cali we don't mess around with emissions. F**k with Governor Newsom, he'll take away your Mocha latte privileges. NOOOOOOOOOOOOOOOOOOOOOOOOOO!

If they do a sniffer test you will never pass. Remember that cats are part of the federally mandated emission controls. It is illegal to remove any operational cat. No I'm not a tree hugger. My MR2 had zero emissions controls on it and having a JDM engine didn't even have an egr valve and wouldn't even pass a visual inspection in many states. I just don't want to see people get hammered by inspections.
