exhaust and emissions
I am thinking about a turboXS turbo-back exhaust system, and am up-pipe. There will only be one cat, in the midpipe. Would these mods fail make my car fail emissions. If so, would it be worth it to remove the parts and reinstall the stock exhaust for the emissions test?
Thanks

Just reinstall the stock parts to do the test. You will fail unless you get a smog tech that doesnt care but that is very unlikley.
