Hello everyone, I just purchased a cheap eBay header for my 97 civic cx hatch. I was just wondering since both o2 sensors go on the header for the secondary o2 sensor, do I need to get an o2 simulator or should I just get the 2nd o2 sensor installed in the exhaust after the cat?

 

you could do either. i would get the simulater. it would be easier

 

or extend wires for the 2nd o2 but simulator would be alot more simple

 

thanks for the help

 

i took mine to a muffler shop and they fabricated one in for me in no time.
