1999 chevy silverado 4.3l o2 sensor code delete

[Chevypickup]

So I have a 99 chevy silverado 1500 with the 4.3l v6, and when I bought it they had removed the Cats. I'm wondering if there is an easy way to mess with the 02 sensors below the cats to remove the error code. Has anyone found an easy way to do this? 

Thanks

some of the higher end tuning programs can turn off the check engine light for things that would normally turn it on. I saw a post about it a few days ago on here, probably can find it from the search bar
