emissions

Hey all, Just wondering i know there are alot on people in NY running catless and wondering what your method is for passing emmisions. The sniffer and visual but more specifically the sniffer. So do you swap for a catted setup right b4 you test or do you "know the guy" thats tests your car...

Hey guys, quick question. Living in NY they do emissions testing on your car for inspection, and have strict emissions results, probably second only to CA. If I was to add a down pipe, and cat back exhaust (with a tune) would the "freer" flowing exhaust, and more power result in trouble passing...

PASSED TODAY!! YADDA!! I was nervous my baby would spit a 'fail'... SO -- IL is no longer using the tailpipe sniff test... at all, never again. They solely did a 20 second OBDII scan. As long as you don't throw a CEL or readiness codes, you are golden. I have a seriously modified exhaust...
