Emissions re install.
 

I'm buying a turbo s5 with a street port and i need to pass emissions in AZ. i was going to buy a high pro Cat and leave it on since don't plan on upgrading it much more for awhile. I know it would also need an air pump but what else? its on an 87 platform gxl. I also have a Complete gxl with a blown apex seal. so i can swap parts as needed. Again both 87. I don't have information on the specific parts yet if needed i will post when i pick it up.

If you have a working air pump and air pump control valve to properly divert the air pump air with a good cat you should pass as long as the car is not misfiring or anything of that nature.

My street port s5 turbo passed with flying colors.
