Default should i order non egr headers

I have a 99 Z28 and was wondering if I should order non egr headers. I would like to take the AIR and EGR off as long as I can be sure that it wont have any negative effects. I am going with ORY too.

Like I said, the egr and air are as good as coming off unless it will have a negative effect on mileage, longevity of the engine, or engine performance.

Well, with an ORY, AIR is doing nothing for you since you have no cats. I personally wouldn't take off the EGR unless you do the LS6 intake too. You will need to delete these 2 from the computer also to keep the check engine light off. I removed the EGR when I installed an LS6 intake a few months ago and just ordered non-emission headers and will be removing AIR then.

No ill effects 'cept a SES light. I would get them if your gonna get the car tuned.
If your gonna mod the heck out of it & tune it then you can delete the air & egr out.

I removed my EGR and it makes the engine bay less cluttered. I say order the race only headers, especially if you are going with the LS6 intake anyway. For now, plug the EGR hole up with a 1 3/8" rubber freeze plug from an auto parts store. Good luck.
