what if your stainless steel dc 4-1 headers dont have a O2 sensor plug?
I just bought this Dc 4-1 header and I looked by the collector and it doesnt have an O2 sensor, what does that mean?

sure you can leave it off. but do you want a check engine light too? btw, what car/year/model is this header going on?

It doesnt come with a sensor, it should just have a o2 bung right before the collector. If not, then put it in the cat or drill into your shiny new header

for 94 and 95 gs-r's, the single O2 sensor is on the cat. U shouldn't have to touch the O2 sensor for your install. header should bolt right in.
