Emission Sniffer (sigh)
alright guys. this is more of an extension from my last thread. I'm getting 2 maggy high flows in place of the four stockers on my 98 expy tommorrow. what i need to know is whether or not this set up will pass the emisions test in TN. I live in the memphis city limits so they still stick the sniffer up your tail pipe.
Thanks!
Thanks!

I had new cats (were not ''high flow'') installed. I think the Magnaflow were around 400 cells per inch, these were around 700-750 cells per inch. Only was failing on NOx (even after cleaning out throttle body and replacing IAC and EGR components).
