So heres the deal. Im about to buy the skunk2 race header and as we all know, race headers completely eliminate the use for a catalytic-converter. my questions to you guys is this; since i wont be running a CAT anymore, what would be the best approach to deal with the secondary o2 sensor. Would welding a bung onto my new race header be the right thing to do? or is there a way were i can totally eliminate the secondary o2 sensor completely? if anyone has knows any good info or links as to how to do this, any help would be much appreciated. thanks guys
