Are green cats better then HFCs or were they specifically made to not throw cel and no performance advantages?

I'm getting Lts and HFCs looking for best setup out right now.

I'm gonNa get tuned by slowhawk and he suggested arh so my question is what's best and what's these green cats about

They are less likely to trip an emissions related CEL but there is no performance benefit to them versus any other high flow cat.

^^^^^^

This!

Since I live in Texas where emissions testing is required, I went with the full Kooks setup (headers, green cats, and mufflers). My last emissions test passed with flying colors without having to "fiddle" with anything.

Wait till you hear the sound of the headers with those cut-outs. I have a post in this Exhaust thread call Supercharged Camaro with Cut-outs (or something like that) with a sound vid.
