its a hit or miss with the tech. if you move the stock cats from their stock locations you will fail... i have hi-flow cats and they aren't in the stock locations but i passed with flying colors

It also depends on how the test is done. Here in NY they don't dyno and sniffer test anything newer than 96 anymore. They hook your car up to a diagnostic computer, and run a test on it. If your car throws any codes or hasn't completed any of it monitors, you fail. So if you get a guy that doesn't care, you could have no cats and still pass. But if they still do a visual inspection for emission controls you'd need the high flows.

I've passed emissions twice with Mac mids, Ory and a Borla catback. (Once with the 224 cam loping). No visual, no codes, no problem.
