I was just wondering what i have. I was thinking about getting the FLP headers for my '99 truck but FLP says they don't have a hookup for the A.I.R. but they do for the EGR i think. I know there is a pipe coming out of my passenger side exhaust but I don't know what it is. can any of yall help me? any ideas? thanks

 

pretty sure 99 should have both AIR and EGR.

 

if your in friendswood you only have the E.G.R.
the A.I.R. is only for Cali. emissions.

 

 

Guess I need to look outside of Cali

I hate this state.

 

Well i know for sure you have egr but like they said if it was a cali truck it would have air. If you ask the chevy dealer to check your vin and his computer system will tell you if you have air or not.

 

thanks yall for the help. i am really interested in those headers but i was a little discouraged when they told me that they don't have the fittings for the A.I.R. so i just had to ask yall what i probably have.

what was the last year for the e.g.r? thanks again for the help....

01 where the last year for the EGR. anything new'er than that doesnt have E.G.R.

 

FWIW, I noticed this weekend that my passenger side header ...err, manifold, doesn't have that fitting coming off of it. There is a hole in the heat shield for it. As far as I know, that was the AIR setup.

MA emissions have been very similar to CA, up until late '03. My '02 GM definitely had the setup.

From what I heard about the AIR setup, is that it really doesn't do much of anything for emissions. I read about people deleting it, and turning off the codes in Edit. But you didn't hear that from me.

 

So I'm a bit lost then. So what I gather then is that my '01 5.3L is EGR. But then again I live in Kalifornia, so that would mean I should have the AIR setup. But my car was also purchased in AZ from what Carfax tells me.

Does anyone have any pictures of AIR and EGR on their car/truck to show the difference between the two? Or any way of telling the two apart
