I live in Oklahoma, so we don't have to get emissions checked. I have a 2000 v6 3.8l Mustang. I bought the car for $3500 at 70k miles (it was a really good) so I don't want to spend more money than I have already done with maintenance (around $1000/ brakes, other stuff, etc) to make the car "better".
Would removing the catalytic converters cause any negative effects on the engine? Would it affect how it runs in a negative way? I'm not to worried about the ECU popping up a code, because I could always take my ECU to get flashed (tuned) to run without the catalytic converters.
