And I'm not singling out Z's. I'm talking any car in general. Catalytic converters are there for a reason, no reason to run test pipes.
And the smell with a HFC resembles a normal catalytic converter more than a test pipe

Cars that smell like burned gas from the exhaust will not pass the emissions no matter what. Crawford makes one of the most expensive HFCs on G35s and I have smelled the burning gasses standing next to the car that had those cats on. Any cat that is less restrictive than stock will not let the car pass emissions. I am talking about the VQ engine. In your case, civic might pass the emissions with HFC because it is already one of the cleanest burning gasoline cars on the market.
