91 header problem

[xczechboyx]

i baught these OBX headers for my 1991 accord EX. First of all in the pic it says OBX on them, but the headers i got dont say anything on it. Plus the inside of the headers where the pipe come togheter looks like a rough job. AND it has 2 O2 sensor spots. I was wondering if anyone can tell me if i got fake OBX headers,and if i really have 2 02 sensors for my car. Thanks

Whether you have a fake OBX headers or not I can't be sure. One thing for certain all OBX headers come with approx. 1.5"X1" metal label either welded or riveted on the outside surface of one of the four downpipes typically around the center. Also the weld job is clean not the rough job you indicated. As for the two O2 sensor locations, that's quite normal for good aftermarket headers in order to adapt to all accord model applications. The DX & LX models O2 sensor location is normally on the front, hidden by the heat shield. The EX & SE models, the O2 sensor is located under the exhaust, near the flex pipe(necessary on all accord models to compensate on normal body flex), right before the cat. converter. One thing to keep in mind when installing headers, make it a one time install. Invest on good copper gaskets, don't rely on the gaskets that comes with the headers, they simply don't last long. You might also consider applying thin layer of the gasket maker (squeeze tube container, design for exhaust use) between all gaskets and header parts to prevent leaks. Need more info let me know. Good luck!
