i have ATP (pt #101212) on my 96 cherokee ive been trying to get it smogged. the smog shop tells me there not legal even though i told them id bring them pictures of the tubular headers cherokees come stock with. ATP says there legal and dont need to have C.A.R.B stickers because there stock replacement. ATP answers there phone once a year and apparently never when the smog shop calls... anyone know what i can do??
