Possible to pass emissions testing with hi-flow cat but no air pump?

No, it is pretty much close to impossible.
The air pump flows air to the catalytic converter to help burn excess fuel that is being heated by the monolithic brick inside your catalytic converter.
Brick inside = catalyst for combustion of excess fuel
To make it complete, you need air to feed the reaction.
A friend of mine had his highly modified FC pass emissions (very clean by the report) by using a Corvette electric air pump and a hi-flow cat. He controlled the air pump with an extra output from the Haltech E6K. It probably would've been better to hook it up to a pot or switch so you can turn it on when you need to pass emissions.
