      The one were all pipes meet is for a wideband I would imagine. You need to install on the primary for the factory O2’s

      I bought a set of used Bellanger headers for my gen3. Sent them out and had them recoated (damn, they look way too pretty to install). I started the install the other day. Everything went great but now I have one question. There are two locations to install the front O2 sensor on the headers. One location is in tube #2, the other looks like the old owner added an O2 bung in the collector piece of the header where the five tubes meet up. Which location is the one that I should use? Does it matter?
