I was thinking about gutting out my catalytic converter and running a piece of pipe through it so that it still looked like I had one on there and would get better sound and maby a little more power. Someone told me that if I did that my check engine light would come on and the computer would run a different air/fuel mixture and would cause me to loose gas milage. Is this true? Also I know that doing this is not exactly legal but what cops dont know wont hurn them.
