I'm not sure what a "test pipe" is ??
Generally if you remove one or more of the two catalytic converters (cats) in the exhaust you may fail testing depending on how strict the testing is in your area.
If your referring to a "track pipe" or a muffler delete then that should not effect emissions test but you may fail on noise output.
I'm in OZ so not up with tests in USA.
