    What about an aftermarket cat? Something that flows better. Will it throw a code or not?

    I don't have any experience with aftermarket cats. Since I have a friend who can modify the PCM I always get rid of the cat and modify the tune.

    loose the cat, summit racing sells O2 sensor dummy plugs that give the PCM a good reading.
