I have a 2001 gt an I used to run it straight pipe. All 3 cats off but I got tired of the hassle of taking it off an on for smog. I live in ca. I had a diff route I'm taking now to save the ca strict emissions. Could I run the two precats with the center/main cat off with a greddy evo 2 full catback system an pass smog? I'm curious cuz the center cat has no O2s on it an I think with it off it's capable of passing an staying under the max limit. Well besides the visual inspection of them physically seing that cat off, the ob2 smog test wouldn't know it's off?
