Does anyone have experience with trying to get high-flow cats through Aircare (BC) or something similar (CARB?)?
High-Flow Cats - Performacne? Emissions?
- Thread starter LITTLE RED COUPE
- Start date
Generally no performance increase. Maybe 1 or 2 HP, could be dyno-related.
I've been told the Comptech passes emissions.... but I haven't tested it.
Don't know about the Random Catalytic converters or others...

Aircare physically looks underneath the car for cats using a mirror on a stick before they do the actual tests. So I don't even know if aftermarket hi-flow cats would pass the physical inspection. P.S. The old guy at the Langley location seems to love NSX's as he had a fun time with mine. Maybe you can sweet talk him into making it pass

I have them... I didn't notice them to be any different. They look like cats. They have a heat shield on them, 02 bungs etc...
