> According to the guy I know where I go… high CO% means your Catty is pouched. He also said reason mine was 1024 and not lower like it should be is because I have a 3’’ high flow ceramic core cat and apparently they dont do as much for “emissions” as a normal flow cat or what not.

See that’s why when I made my exhaust I made provisions so that I can double up w/2 cats. My resonator can be removed and in place of it I can put on another cat. So I got cat 1 and cat 2, pass w/flying colours everytime. In street trim I just put on a fake cat and a test pipe. In track trim I just unbolt everything.
