They're supposed to visually check for them here also, but depending on who you know/where you take it, they may overlook it :cool:

They used to have state run inspection stations here for a few years and that was a PITA. Glad they got rid of them and went back to letting repair garages do them

I am shocked Oregon doesn't check for their presence with the mirror on the stick thingie.
Nah they never have. Emissions here takes 5 minutes st the most, and if you go in the middle of the month you can be in, pay the fee for the test and registration and drive out with tags in 10 minutes total at the most. There’s lane cameras that you can look at online to see when there’s no line and that’s when I go. All they do is hook up to the OBDII port and take a reading of the monitors. Super easy and zero inspections.

Amazing, given the big government orientation of your state. Here, the guy does the same ODB hook up and what I suspect is a check for DTC and monitor status, but they occasionally walk around with the mirror verifying the cats are there. I am not sure what triggers the visual inspection as I have had it done both ways. They also have a tail pipe sniffer, but I have never seen it employed. Probably a secret when each thing is used or not... ;)

In this New York your car has to be hooked up to a machine to verify that there are no codes logged in the ECM if your clear its good. I leave the cats on , with them off it stinks but there is a way around that with advance timing at idle.

Pretty soon the nazzi's will be asking "Vere's your papers"
Piss ass politicians here. Wonder how they get elected.

I didn't say you couldn't.

I used to have to pass emissions with it and had a small mid-pipe with cats that I would swap out instead of the non-catted X-pipe that's normally on it.

That was back when they would stick a sniffer up the tailpipe for the test. With it being before OBD2 it only has the 2 upstream O2 sensors.

Our 02 mustang runs a catless x-pipe also, but no longtubes, only shorty headers. I run MIL eliminators plugged into the harness at the downstream O2s. I uses to just have them turned off in the tune, but when the emissions test was done it was able to tell that they were disabled, or got no readings/communication with them.

It's been like that for years and I'm sure with the technology updates of today that tuners can probably get them configured to pass the tests, but this works and I'm not worried about changing it.
I have my downstream sensors disabled and no reporting so it’s like they don’t exist and have been that way for a while. Passes emissions no problem. Still have cats but really only using them so I don’t smell the raw fuel from the exhaust. Long tubes don’t mean shit these days for emissions. Just a hassle to install if they aren’t a good quality set.

No need for timing changes either to pass in NY. Had my car tuned for 2 years now got a sticker every time with headers and cats and no rear o2 sensors.

In NJ they hook up the obd and check your gas cap for any leaks. You also drive over a camera in the floor--this checks for cats. You can't have any codes, pending or otherwise or you fail. This is through state motor vehicles. You can pay to have it privately done too. Any vehicle over 25 yrs is exempt.

Big government orientation of my state? It’s no bigger than most any state, much less in lots of areas especially things like vehicles -unlike states that have things like “safety inspections” which are more government getting in your face or cameras looking up your undercarriage for the absence of cats. Now California, that’s another story.
