If EGR was such a good thing to have, why did GM remove them starting in 2000 or 2001 (can't remember which exactly)? And the AIR pump only runs a few mins anyway to help heat up the cats. If you plan on doing future upgrades in exhaust, i would definately remove them. For that matter, if you plan on doing any mods at all I would remove them. Your engine compartment will look better, be easier to work on, and your car will be lighter. All positives if you ask me.

Firebirdfan it all depends on where you get your car inspected. Yeah in some states all they look for is a cat and a stock appearing muffler but I have seen others actually look at your readiness code, and for proper operation of ALL of the emissions control devices. It all depends.
Like I said unless you are trying to be a drag race champion and look for those few tenths, then you can drop them. And if you are that worried about lifting the nose put in a chrome molly K member, upper and lower control arms and a manual rack.
wht01ws6ta I drive an 03 RSX type s during the week for fuel economy and it has EGR. You drive your car every day and race on average how many times a week? There is a big difference between your DD and your race car. I can gaurantee that your drag car will not see nearly as much time as your DD.
samson_420 Like I said unless you are trying to win a Best in show or if it pisses you off that much to look at it. Or move the hose through the fender like the wire mod.
ghardester and spm4520 the only one I would remove if I didn't have to worry about inspection would be the EGR simply because all it does is cool the cylinders down under cruze and low load and I will agree with what you said. GM didn't think it was important enough to keep it in 01 02.
Like I said AIR does more than warm up the cats faster, it keeps them alive longer by leaning out the cold rich mixture. Unless they are not there, then you can flood the air with NOX, HC and CO.
You don't have to listen to me or do what I would do. It all depends on the person and what you plan to do with the car. If I offended any one I apologize but don't call my information bull sh*t if it is backed up by facts.
I'm not here to argue or to save the world just tell the man what the systems do and let him make the decision for himself. Thats all he asked for.

If you dont have to worry about emissions simply get rid of both. When I get a LS6 intake, my EGR will be gone, and after I get LT's for Christmas the AIR pump will be gone as well. both of them serve no purpose to me besides clutter the engine bay, and add weight in all the wrong places.
