Any Vehicle In most parts of Canada and Usa does not need to have a Catalytic Converter If it was made Jan 1,1995 and earlier.It will flow better and probably get more powerand mileage
Yes, That year MUST have 1 are it will not run right. No way around it.
No, that will not work. A restricted catalytic converter will need replaced.
There's no possible way to pass inspection with a bad catalytic converter, if if you find out you have a bad catalytic converter during your inspection you have a chance after you after you have replaced the catalytic converter and the inspection no no charge/free!!
It doesn't need one to run, but it probably won,t pass emission tests
If it came from the factory with a catalytic converter then it must have one
