Default No SES light after headers?

Got my car back today from having long tube headers/ory today and my car is not throwing any codes. Can this be right? I drove it for about 20 miles. The o2 sensors are gone, the cats are gone, and AIR is gone. From what I've read I should be throwing some kind of code right?

It will come on, you might just have to wait a little longer.

if you disconnected the battery it will be a while before the systems are ready and therefore able to report that the **** aint there. Its some amount of miles i believe.

Or like in my case it never came on. So i got the car tuned to find out it had already been tuned for bolts on, Nitrous, and a stall... Guess the car has already been down the modded route. When i got it only had 3.73's wondered why it had gears when the rest of the car was stock down to the air filter..
