We have installed a ton of headers on the 5th Gen Camaro with high flow cats and have not had one person call saying they have failed emissions testing. The newer cars are all OBDII with no sniffer. You will have to have the car tuned or you will get a check engine light, instant fail. Plus you will not get the full benefit of the headers without a tune.
