    That’s a flex pipe. Behind that there’s a cat and the second o2 sensor. I wouldn’t doubt there’s secondary cats inside the muffler.

    There shouldnt be any additional sensors. These would be passive. Otherwise folks would get a cel from just an exhaust

    Agree i posted ot here by mistake.. i asked the mods to move it somewhere earlier, maybe the exhaust or gen 2 section. It actually ended up being an informative thread.
