alright i have a quick ? i'm finishing up my custom exhaust and custom test pipe for my 04 oz and i see that road race has one with a cell thingy in it for the o2 sensor

now should i buy that ROAD/RACE "Check Engine Light" Eliminator (For Headers/ Downpipes) so my light won't turn on? would it work?
