    Yeah, no. Cutting the cat out or straight piping the exhaust does nothing. You wont gain anything but some bleeding ears from the drone of the muffler-less exhaust.

    The cat converter is there for fueling on some of our cars, you cut it out, say goodbye to fuel economy. I don't know what kind of car you drive, but just leave it the way it is.
