Cav. Header

OK i searched but could find the answer. I recently found a cavalier header for slae in me area. I already told him to call it sold so here are my questions. I know it fits fine and everything, but there was the O2 (i think) sensor problem, where you have to get a new port wleded in? If so where does the new spot need to be? Pics would be great. My next question is ive read on here that it makes your computer throw a code regarding to a "low catalyst efficentcy" or somthing. Does this always happen, if so how do you get rid of it?

Ok ive gathered so far that you need to have the o2 sensor port to the passenger side. But are there any codes thrown?

[alerojack]

shouldnt be as long as your o2 sensor is hooked up and there are no leaks or anything. should be good.

Thanks! Ok now once its all done, how hard is it to install? Do i need al the gaskets and stuff or will the stock ones work?? and how likely is it ill break a stud in the head trying to undo the bolts.

how likely? not likely at all if you're careful. WD40 and wrench wrench wrench. Get a new exhaust manifold gasket and you should be fine.
