I have a set of pacesetter headers for my 3.8L '01 maro. If anyone has these same pacesetter headers maybe you can help me out. Since I will be putting the headers in I figured I would do a few other things since I am there. i.e. spark plugs. I am gonna replace the o2 sensors as well. Can anyone give me information on the o2 sensors? Like how many I will need or type or which ones will work with the pacesetter setup? Thanks to all who reply.
