The easy answer is yes and don't know. Simply physically putting pipes in place of the cats is not an issue. I believe there is an O2 sensor after the second cat though and how this will be affected I don't know.
If the test pipes allow for C02 sensors you may have to install anti-foul extenders to get rid of the engine code. Otherwise it should work but the engine is not getting appropriate signals and will have a SES due to it.
