Hi David, Yes you can pass emmissions in tennessee, the only state that won't is california because of their special requirements. It is legal because it has the catalytic converter in the same location as stock and your stock o2 sensors go right back in to stock locations as well. It will even bolt to your stock midpipe if you want it to although the goodwin midpipe mated to this header along with a freeflow muffler that Brian offers here will give much more power. PPE claims 12 whp and thats exactly what it feels like. Thanks , Tim
