Hey yello91silverado, My truck was supposed to pass the same way. Your truck is pretty low like mine so maybe they won't look under it either. Most of these inspection places rely on the rear 02's to code out if the cats are bad or removed. I disabled all of the items that kept the check engine light on and I was able to pass with no problems. They even said the new motor showed better readings than any of the 97's with smog equipment. I'm not running any air injection, rear 02's, fuel purge canister, etc...and I live in a pretty strict area. We have to get anything older than OBDII dynoed for a sticker.
