Free/High Flow Cat Converter

Is there a Free or High Flow Cat Converter for the SPI? Most of the header setups require the removal of the cat thus making it illegal by California standards. I realize that you can technically buy a high flow cat for just about ne car, but you need to mount the stuff yourself since it will be different. Does any company make one specifically or one that fits the SPI[SE]?
