Anyone have any experience with passing NYS emissions test with one high flow midpipe cat? Can it be done? If so which cats are you using?

my vert used to pass no problem with a single catco high flow converter, I would always end up changing plugs right before
anyhow, not sure if made any difference.

the emissions limits for these cars are sky high

Okay. The mods moved this front 3rd Gen Tech to Northeast forums. Thats fine, but know I need to specify: Will I pass NYS Emissions with just a High Flow Midpipe Cat on my 3rd Gen RX7

take it for what its worth, but my car originally had 3 converters, and I replaced it with the one and still passed no problem.

No experience with NY, but my FD passed MD emissions with just a Random Technologies high flow cat.

well the good news about your location is that if it doesnt its not hard to find a place that sells you the sticker without even puting the sniffer on
