I'm currently running the racing beat single pipe exhaust system. I have the airpump removed also. If I throw a highflow cat on there, do you think the car would pass a visual emissions inspection, or would they fail it cause I don't have the air pump? Thx.

Depends. I don't know how close they do the visual check, even here.

I don't know why they even do the visual check.

Most new high-flow cats do not require an outside source for O2 (no air pump needed). They are made of materials (platinum?) that can generate their own supply of O2. Of course, I'm not cat expert because I don't have to pass emissions
