For a six I'd put the bung on the header after the collector, but then this becomes a two meter system.
I only put one sensor in the header on the passenger side. Probably not ideal but it seems to be working just fine.
That's a perfect spot, with the bung facing upwards at 12'oclock. On the 9146 header collector...you are sampling 3 ports at once= good.
At the rear of a T4 heat exchanger, it will be good to capture 2 ports...so have your fabricator/ welder look for that spot Maybe just at where the 2 tubes join up into the muffler. Otherwise you will only be sampling 1 exhaust port = not optimal, but will work
