    To cat or not to cat that is the question

    I do live in an area that requires admissions but every time i do them all they do is stick the machine into the obd 2 chip under the steering wheel. Should i take a chance and get off road headers or be safe and get catted ones and if i do can i use stock cats. Thanks

    Depends if they do a visual inspection as well. If they do, you have to keep the cats, or they will fail you. If they don't, then you won't need cats. You can get an ORY and get O2 sims, or have the codes deleted with a tune so they don't show up when they scan your OBDII.

    go to speed inc, its about 10 miles from chicago, not far from woodfeild mall.
    i have a cam, long tube headers and no cats and passed. speedinc will set youre computer to pass everytime.
