Re: Opinions/Advice re: catalytic converters

I did this to my car years ago. Even when I had to go through echeck, it wasn't an issue. I actually took the cat converter and punched it out hollow with a piece of pipe, then reinstalled it. Eventually I just replaced it with a piece of straight pipe.
