I removed the cats and disabled COT, but I hate the sound of cold starts while the Cats are warming up. The combination of my exhaust and no cats makes it crazy loud. How do I disable the cat light off?

Go to Engine, General, Catalyst.
Raise the enable to 490 fahrenheit and disable to - 140 fahrenheit.
Then, go to Engine diagnostics, Exhaust, Disable catalyst test.
I don't have that option in mine. Under engine and general there is only engine displacement options and that's it.

I hope that works. I've never done this so please bare with me.
So I found it. I had to search for it in the parameter navigator and it's in a hidden folder called exhaust. This folder doesn't appear anywhere else for some reason. Really strange. Thanks all.
you are probably using Basic view. Change your setting to Advanced
He is right, it's not listed under the regular exhaust tab even in advanced view.
If you look in the navigator there is an exhaust folder there that has it. Both the regular and beta version on my computer show it there. My beta is the latest as of today, so 4.4.4X.

bumping this up. Looks like this parameter is now totally removed from the latest versions.
Been that way for anything past 4.10.6.
Has anyone found a work around for the parameters not being available anymore?
You can try an older version, but some of the older versions won't open newer cars. Just have to try your luck. There is no work around other that what I've suggested.
