Is there a vacuum line that is supposed to go from the air diverter valve to the air bypass valve? Or do the valves just remain open? Also the airflow hose to the cats has been cut. Do I need to get a long hose and run that to the cats? Or could I pass emissions with it cut? I just had my complete exhaust done the other day and just found the smog pump assembly & put that in. I had the shop put AP cats in with 2&1/2" flowmasters and turn down pipes at the end.
