What exactly does the inspection entail is the first question. Do they look under the hood or just a sniffer? If just a sniffer, I'd get the race headers and the LS6 intake without EGR. You can then delete EGR and Air. As stated, you'll have to modify your tune to make it all work. If you get the emissions headers, the welded emissions bungs will vibrate and eventually fatigue--falling off and leaving a big hole in the tube. Ask me how I know. Have fun with it.

Like stated previously, the race headers is what you want if you are deleting the AIR and EGR. I got Kooks LTs, but for some reason ordered an LS6 intake with the emissions...so I had to block those off (doesn't look the best, but gets the job done).

yes you can, just order "race headers" and a catted Y and you will have what you want. Then just reprogram the car for no AIR or EGR...an 01/02 has no EGR anyways...different cam/intake/tune...but nothing you can't overcome with a little effort. You definitely should reprogram the car for the lack of EGR and to turn off the AIR pump related check engine lights. Plus while you're in there it's pretty easy to turn off the rear O2 sensor checks and such too...then it'll never fail the plug in test.
