Cats Delete?
Hey guys I was wondering, a friend of mine told me that you could just delete the cats with like efy live or ls1 edit, is that really possible? Or should I just get some 02 simulators?

But why not let your friend do it? He seems to have the answers.

I use O2 simulators to avoid throwing codes, they help avoid codes whether you run cats or not, and I do run cats (the biggest I can find). It's illedgal not to, and while you can get away with it pretty easily, I believe its also "cheating" (Yeah, who cares? But I'd know). I also know from back to back dyno tests that it costs me 29 RWHP, but I still run cats.

Just to clarify: if you remove your cats, a few days later you will get a check light from the rear O2 sensors. The computer compares the front and rear sensors, and looks for a difference (caused by a properly functioning cat).
So, you have two choices: put O2 sims in place of the rear O2 sensors, to fool the computer. These work great, and do not cause any issues at all. Or you can use a pcm editor to delete the rear O2 sensor inputs to the computer, so it ignores them.
Either way, no codes, no erroneous signals - just a really bad smell coming out of your exhaust, and a really nice sound. 12hp gain on a stock car.
