Ok first of all, does the 02 sensor plug into a peice of the manifold or a peice of the first cat? Since I just bought a bonez RP there is no hole in it anywere so I was wondering if I need to cut a whole or the 02 goes strait into the manifold?

 

Strange, mine came with a bung hole Where did you get the pipe from?
