[Hotwheels Camaro]

Hey guys, I've been looking into getting a cut-out on my car. It's a 2000 Camaro all stock until the muffler which is a Flowmaster 80's Series. I've heard that with a cut-out, it will throw codes because of lack of back-pressure. Now I remeber reading some where that you can have a 1" to 1.5" pipe connecting the input pipe to the muffler to the right exit pipe of the muffler. Now would this setup help prevent these codes for no back-pressure. How would this sound compared to a cut-out. Your input is helpful. I want to do one but I don't want problems with my computer. Thanks
