    a Resonator is more or less a glass pack.
    performance wise, all catbacks make about the same power.
    i always suggest the hooker or magnaflow.

    Resonators have a straight through design which has the least amount of flow and sound restrition. (flow well but dont sound as refined) A muffler is the opposite. A muffler will have some type of baffle in it to help reduce sound. (will not flow as well but will sound much better)
