    Nah, I wouldnt do it unless its plugged up or something.
    You won't get too much power out of it, and you'll have to worry about the fines that could potentially be charged to you.
    Unless its a race motor, don't bother.

        It will make a difference actually. Not a big one but it will. Your car will also sound better.

        DaN, how would he get a fine if the cat is still there but hollowed out? Please explain, lol.

              if you're going to hollow out your cat, put straight pipes through it when you're done.

              gas likes a passage that stays the same diameter.

                Now that's seriously too much work... just get a set of straight pipes made and swap 'em out for inspection... it's one day versus 364 (or 5). Part of owning an "illegally" modified car.
