ok so i might be buying a tii withall emissions removed. i need to pass a sniffer test in my state for now. The emissions laws willl be repealed at the end of the summer. I read somewhere that you can pass if you run a cat with an airpump feeding into the cats air tube. Any experiences with this? O if it matters, i live in st. louis missouri.

you need a cat for sure, and you need the air pump for sure. lowest emissions is with the air pump air plumbed into the stock spot on the intake manifold, which goes to the exhaust ports. if you take off the acv/block off plate, theres a round hole, air pump gets plumbed into there.

yeah, my car failed emmisions i had to put in a stock air cleaner for it to pass if you dont have one wrecking yard is your best bet i got mine for $35, and your catalytic converter has to be there...
