Nissan 370Z Forum - View Single Post - Good alternatives to OEM catalytic converters?

Currently running test pipes on my 2012, just read that my county will begin doing emissions next year. Emissions have never been a thing here so this is an area I'm fairly clueless about.

The default will be to get OEM cats but I'd be interested in seeing if there are less expensive options that will definitely pass the smog test. A lot of these high-flow cat options look great, but I'm unsure they would actually pass?
