Hey what's everyone doing about this in their m30 swap? I am using e34 downpipes and am trying to use the e30 exhaust system. Can I put an o2 bung in just one exhaust tube?

Sure!
Mine was actually placed right in the collector where the two pipes join.///Monstrosity. (OO≡≡[][]≡≡OO)

Is that a collector under the heat shielding just behind where the downpipes start to bend upwards? If so ill do my best to put it there!sigpic<< wreckedComment

Yes it is, think more like an x pipe. The exhaust shop cut my collector in half when they did my exhaust, so I just had one put in the side of my exhaust facing outwards.Comment

In my swaps i always put it in the middle of the X pipe so it can sniff both cylinders 1-3 and 4-6 evenly.Comment

Wherever you put it try to have it positioned between 9 and 3 oclock so it doesn't contact a lot of moisture like it would if it were placed near the bottom of a pipe.Never argue with stupid people, they will drag you down to their level and beat you with experience. -Mark TwainComment

For future reference, here's what a stock e30 o2 sensor bung looks like welded into e30 m30 downpipes... About 1/4" gap that needed to be filled because of the discrepancy in tubing size

I do not know how well it flows. We cut about 1/2" across oval into both tubes. We used the bung from stock 325i downpsigpic<< wreckedComment
