after changing my exhaust i got a CEL
i just changed my whole system to a warp-speed y pipe wit a magnaflow cat and a stillen axle back and now i got a CEL saying (from autozone free OBD2 scan)
code:P0420- the PCM has determined that the catalyst system efficiency for bank 1 is below threshold for the current engine operating conditions.
Definition:Catalyst efficiency low bank 1
so does this mean i have to go back to the stock y pipe with the 2 pre-cats? please help me out guys its been a year with out state inspection lol. i dont kno how much longer i can get away with that.
