    The truck has two sets of cats, so depending on which cats you eliminate you'll do 1 of 2 things.

    1. if you remove the front cats, you'll throw an o2 code.
    2. if you remove the rear cats, nothing will happen.

    Either or will increase the sound, and peak HP. You MIGHT lose a little low end, but IMO not enough to make any kind of real difference. You're just moving the torque higher up in the rpm range.
