Macs O2 location The big brown truck just dropped off my Macs midlength header system and I noticed the O2 bungs are right directly behind a single primary tube on both sides. Will this be a problem for my sensor to be reading exhaust from just one cylinder? Do you get what you pay for when buying headers for LS1 cars or am I just mad at myself for being in too big a hurry to wait for a set of KOOKS or both?
