o2 sensor mod?

i haven't found much while searching on what people are doing when running no cats. i know that some people use "star" to permanently disable the o2 sensors, but has anyone messed around with spark plug non foulers?

any other options out there? i HATE fault codes and CEL's.

Defoulers work or they don't work my does not..I'm still getting CEL with my defoulers. You can trun them off with a Tune. I hate to say it but KLEEMANN is the only company that I know can turn those CEL off and still be able to pass emission.
