had this academic discussion with a fellow ferrari owner about removing the cat converters from old ferraris, for example 30 year old 308s. Since there is no smog requirements as far as I can tell for antique cars (in texas defined as cars 25 years old or older), and such cars do not require annual inspection, but only payment of a five year registration fee, I say there is no legal impediment to removing them and thus having a free horsepower increase (I guess it would go from the 240 US verstion to the 255 european version). I also think it would be relatively easy to do: wouldn't it involve just removing the cats and getting some bypass plugs or something for the openings in the sides of the muffler. Then the question is could a regular muffler shop make and install that bypass or plug. My friend says it can't be done. well that's our discussion who is right?
