I did this for about 5 years and it was a pain in the ass without a lift haha
What I also don't understand is once a 2006 vehicle is 25 years and older, how in God's name will NYS still require it to pass OBDII testing.. Hell by then OBD II testing will long be obsolete, non-existent along with OEM original catalyst components as well.. Doesn't make any sense as far as I'm concerned
Very well unknown indeed, especially when original OEM parts will no longer be produced for the 2005-10 models long before becoming 25 years old lol.
Then I suppose the only way of getting around it, is by reinstalling the original catted mid section just prior to inspection..

Are his the same ones as you have or different ?
On my 76 firebird if I decide to use it regular and go over the 5K mine limit I would have to put all of my smog equipment back on. Pumps, cats, pcv and pass a sniffer test. Remember, these rules/regulations were put in place to keep us from doing the shit we do to protect the environment. Whatever you need to do to get by them is the price we just have to pay.
I used to switch my midpipe & tune every year for smog. Then I made these electronic cat sims and wired them in.
That worked for a couple of years but eventually one of them failed. Instead of making them again I went the ones you see now. Yes those links are from the same company but not sure if they are the exact same ones. I originally purchased the regular straight ones but had a fitment issue doe to their length. Then I just go the right angle pipe/extension thingy and screwed them into that. I think there is a right angle one with the minicat in there not like my two piece set up.
I think it would be easier to run long tubes and a catted mid pipe all coated black or silver (in order to blend in) than pass smog with no cats as well as a visual inspection.
Once the cats and headers have a little road grime they will blend right in. Especially if the inspector is using a mirror to look under the car.
I would be open for and willing to run long tubes, again it’s not the visual part I’m worried about. I need it to plug in OBD and say everything is there, running and fine. I’ve also read high flow cats aren’t worth the investment as the stock cats flow well(don’t know if this holds any truth)
I’d really be willing to try the setup pentalab suggested with that mini cat, but an investment in long tubes and a new mid pipe to have it not pass NYS would really mess me up.
Has anyone passed NYS or equivalent with long tubes and cats or long tubes without cats?
I know there are settings in SCT's software for emissions. My tuner did something that he won't say, but essentially I roll up to OBDII smog, let them plug in, and it passes every time. With O/R pipe and rear O2's plugged in. From what I understand, he basically adjusted the emissions to tell the smog machine my car doesn't require a catalyst test. With the rear O2's plugged in, all my emissions readiness light up green. I don't know how it lies to the machine, but it does. The new owner of my car also just had a smog done on it a couple weeks ago. Passed. I know it won't pass visual but I did have a HF catted midpipe. Only thing that sucked about that was once and a while it would throw a CEL, rear O2's didn't seem to like the HF cats. It was always driving on glass to get it to the smog station before the CEL would trip. Not sure if an inspection would be able to figure out its secret if the HF catted midpipe were present on that tune. Cats are present and the machine says it passes, what more could they look for?
what your tuner did no longer works in NY, they changed the software about 2-3 years ago and the system now "knows" what the car should have as far as active monitors as I understand it.
So if the mini cat doesn't function like a real, full sized cat.. How does it function any different from a non-fouler ? If non-foulers function in the same way and can also pass ECU/OBDII port emissions testing, then how does the mini cat provide a better alternative over non-foulers
That's a whole nother thing NY probably didn't think about. Because our law makers are so fantastically good. They do such a great job thinking about the long term impact of the laws they pass.
Non foulers won't work with no cats. I used JBA ceramic LT's and mating JBA hi-flow cats. Once in a while I still get the odd P0420 / P0430. My fix for that was the right angle non foulers. Some tuners can carefully tweak the transit timing so the 420/430 never appear. Some have had to use 2 x non foulers in series, typ a right angle NF 1st, then a straight NF, then oem 02 sensor.
If you don't have a catted mid section, non foulers won't work, hence the use of the mini cats. The rear o2's want to see a cat.. mini or full sized.
The ceramic jba LT's and mating high flow catted H was the one mod that actually worked. The increase in low-mid-high rpm tq was blatantly obvious. It was also a lot louder, + drone @ 1900 rpm, so in went a pair of welded in M80's... resonators, problem solved. The JBA cats are much bigger diam, like 4"... vs oem cats. But the jba's are shorter. Bigger diam is way less of a restriction. But the entire internal volume of honeycomb material is aprx the same. I can push down hard on any of the 8 primaries with my fingers, and not burn them...that's after having the blower on 2 blocks away.... b4 pulling into driveway.
Ceramic LT's and high flow cats have some other advantages. Heat in eng bay dropped a ton, like 40 F. Oem exhaust manifold runs stupid hot, and the oem cats at bottom of eng bay... just cook the eng bay, esp @ wot + 1800 deg F cat temps.
We don't have obd testing.... but the next large town over does. The 420/430 is more of a pita, and easily cleared on the fly with the aeroforce gauges..plugged into obd port. The SS right angle non foulers solved that issue.
Cars with no cats have a bad exhaust smell to em, imo. I believe some of the success of my lts is from the ceramic coating inside and outside, the hotter the gases are inside, the faster they flow. High flow cats are less restrictive vs oem cats. Lt's scavenge really good vs oem manifold. 2.5" hole inside the H section works good.. scavenges a 2nd time. The lt's used 1 5/8" primaries, and 2.5" collector. They also had em in 3" collector. The 2.5" collector just made for simple plug n play.
Non foulers have worked on two different 3v's cars I've had with no cats. Passed Gwinnett County/Georgia emissions for the last 6 years.
Coyotes seem to be more apt to detecting changes in emissions equipment. Simply adding non foulers on a catless Coyote car doesn't usually work. Something has to be adjusted in the tune and a mini cat may need to be used in conjunction.
What year is your Mustang, is yours a Coyote or 3V ? From my understanding, non foulers do work on the older 05-10 3V cars even without cats.. Coyotes on the other hand are a different animal..
That's my understanding as well.. Therefore if the non-foulers work on the older 3V's without cats, then why fork over nearly $100.00 for O2 mini cat extenders to begin with

Seems to me that NY is just as bad as California when it comes to emission laws lol.. Although I'll always consider western NY as home, I'll be in no hurry to move back to say the very least
