I have an 03 Ex coupe (K24A4) and im planning on purchasing a DC Sports Stainless steel brushed headers. If i install it, would the CEL turn on if the O2 sensor isnt on the manifold? I searched for it and found something similar on another thread but it didnt solve much of my answer because it was speaking on something else. Any information or tips would help. Thanks.

 

Yup. unless you fool the 02 that the sensor is in there. but this is just a header only so its fine. plus i think it should be CARB approved. So whats the point of not putting it in?

If you want it out this http://cgi.ebay.com/ebaymotors...wItem shouldn't turn ur light on. Never tried it.
