its for emissions, sup it warms the cats up for better burning etc... if you took the system off it would throw a code, so ud have to get a base tune and then you would pass.
you wouldnt have to worry about under hood check as to the pump it self is hidden...they would literaly have to take off your fender to see it.

EGR=Exhaust gas recirculation. Sends some of the exhaust back into the intake manifold to be re-burned with the fuel. This helps reduce oxides of nitrogen in the exhaust.
AIR=Air injection recirculation (I think). Pumps air into the exhaust manifolds on startup to help the catalytic converters warm up quicker.
Nope. Removing any emissions component is illegal. However, if you remove them and have someone with a programmer delete the related trouble codes from the computer you won't fail the plug in emissions test, this is what many people do.

I honestly don't know if removing those two components would alter the reading one way or another. I can't imagine it would change it that much but I have been wrong before.

I have removed my air pump. Kept the EGR since I'll remove it when I get my LS6 or Fast intake and passed NJ emmisions no problem and here is similar to NY. Just clear SES light or delete the code with a scanner before you go to the DMV

I wouldn't think removing the EGR would be considered illegal since 01-02 F-Bodies had no EGR nor did 98+ Vettes.

WOW some of these posts are so wrong its not even funny.
1. IF you remove ANY of the emission system (Included but not limited to cats, air pump, EGR) you WILL fail emission and will throw a Check engine light.
2. For the guy who said the pump is hidden yea it is, but the hoses commin off the manifolds are clear as day to see where there suppost to connect and for any decent inspector block off plates will stand out like a sore thumb.
3. Yea 01-02 and vettes didnt have EGR but that doesnt matter, the Emission sticker on YOUR car will say its suppost to have EGR and will have the ports on the manifold as well.
OBD2 testing is not simply plug it in and if you dont throw any codes then you pass. Thats only half the test the other half is a visual inspection and this is true in MOST state. And unless you know someone the odds of an inspector letting it "slide" are VERY unlikely due to the heavy fines if you get caught doing it. Especially since this adds ZERO horsepower the only real plus is that it helps clean up the engine bay but unless you show your car thats not a huge deal either. And unless you get LT's it will probally end up causing you more trouble then its worth IMO

Also, you can't just clear the code with a scanner before you go for inspection because they computer will show a "not ready" status when they plug in to test it. You would need to actually delete the codes from the computer entirely.

Listen to this man!!!! Also, you CAN tune the light out but it still WON'T pass the visual!!

1st off -I have removed the AIR and EGR and have passed NJ emissions 1st off I have done this for 3 different occasions here in NJ
2nd - There is no under hood visual inspection here.They don't raise your hood and i'd doubt even if any of them did, they would even know what a EGR is! They only use a mirror to check under your car to see if you have cats
3rd- Heavy fines? Nope! Who is going to know you removed something on at least (02) a 6 year old car? They don't know how many owners the car has had. Every state is different though
Every LS1 vette 97 and up had no EGR. The cams in these motors were the same in 98 then changed for 99- 00 F-Bods then again in 01-02

2. Yea there is a underhood test as some imports have the cats right off the manifolds like some civics so they have to pop the hood to inspect all the emission equipment. If the inspector knows what he is doing he is check that the car still has ALL the emission components, and there computer tells them what each make and model is suppost to have. And that makes no sense why would they check for Cats and not any of the other emission system? And I know several people who failed due to no AIR or EGR.
3. The fines I mentioned were not for the driver/owner its for the inspector/shop which is why they are so picky with the testing. A shop/inspector can loose there license if they get caught deliberately passing a car that is not "legal" according to inspection.
Of course there are ways around it, and ALOT of people do so, but im talking about from a 100% legal standpoint

not sure about in NY, but MD they did only the Plug in test
I had an o/r H on my stang, but had mils, so no light, the inspector noticed I had no cats, butj as long as I had no light on in the dash he didn't give a crap. May have been a nice guy, or he didn his job, checked for codes.

i wasn't crazy about feeding exhaust into my intake stream so i just sealed the EGR opening on the intake manifold but kept the tube running into the hole so its still looks functional. i had codes tuned out as well. it still looks exactly the same and throws no codes...utter perfection lol
