Official 3rd Gen Hemi thread

What are you guys doing regarding the cats and dogs? Kidding, just the cats. I presume since you don't have to meet emissions you're not running them. I'm interested in doing a cat delete (never did like those critters). I've been looking at O2 simulators, but so far the info is sketchy. I suspect it would be in the threads listed but finding it is daunting.
