i live in newyork...so i need to pass newyork emissions test...i want to go catless. so my question is, is there anyway to pass this..other than them checking to see if there still one on the car,does it show up that the cat was deleted when hooked up to there computer and if so.can a tune make the computer read a cat still being there to pass the inspection

 

without a cat, it won't pass.

 

go catless after your next test. how often do you have to get one done??

 

NH they dont check. They just plug in the computer and scan for codes. No codes = pass. Make sure your DP has an angled bung and you should be fine.

 

we get checked once a year..i might just have to go hi flow to pass and make things easy

 

not true, pretty much what mkulrey said

 

If they physically check for a cat then get a hi flow. If they don't, then get catless. If you get an angled O2 bung it will pull the O2 sensor out of the exhaust enough to make it read lean, which will make the ECU think that the cat is still working. You can also get a tune and remove the cat efficiency code.

FYI, doing either of these things is technically illegal.

 

Maryland is the same way no light no codes=pass see you later bitch's

 

Connecticut is the same way as well.

 

mechanical cat bypass?

 

i am a state inspector here in VA. down south we dont do emission testing, but we check to see if theyre there if not you fail. And i dont care what TRICKS you guys think you can do you may fool the pcm but you arent gona fool that five gas analyzer that checks for every contaminant there is in your exhaust mixture

 

True, however almost all inspections only use the ECU for a Pass/Fail check. I know that California is much more strict and I think they may do exhaust gas checks plus ECU checks, but everywhere else is pretty much ECU only unless you have a pre-OBDII car.

 

right

 

no tricks in ct, its either have a cel you fail, or dont have cel you pass.

 

x2. they also dont put a snifer up my exhaust either.

 

Or get A "test pipe" made and swap it back and forth for inspection time.

 

or keep the stock dp and just switch it for the test haha not too difficult

 

coming from me since i live in NY i just switch mine when the time comes. Where i bring my car they make sure you have everything. takes about 20min to change.
