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?

i haven't look at the stock one i'm piecing everything together and finally came up with some money so help me out, lol

 

If you're making everything custom, why not put a bung in there near the stock location for the sensor?
