I live in Ohio and cars have to pass an emesions test. Do you think there is any way a turbo car with no catalytic converter could pass the test? There are some gas addatives but im not sure if theyed help with no cc.
If the emissions shop is legitimate they will check for a cat. If not, then it still really lowers your chance of passing. A catylitic converter makes all the gases go way down, really it depends on your state and the shop that does the test. Get them to run it at high RPM's, it helps.
