If you have a 986 without secondary cats then your Primary sensored cats are not in the header but directly after the header, in the location where us 4 cat folks have the 2ndary unsensored cats.
So if you remove those you will have NO cats at all and that could be a problem because the O2 sensors will have to go elsewhere and you will have the engine light on and will not pass emissions.
