Hi all,

I'm in the process of purchasing a 93 GT. I have a friend that has the exact same car. He took the stock H-pipe and hollowed out the cats. Now, I would never do this as this would be breaking this states pollution control laws. If I was to use a set-up like it I would only run it at the track. I was just curious as to how the hollowed out cats will effect his O2 sensors? I have also not heard his car run with the hollowed H-pipe. Would it be way to loud?
