Where would be the best spot to put the O2 sensors in this crossover?

you want it up a little bit more than halfway.......like 10 or 2 oclock position to keep it from getting moisture in it from the exhaust.

Sorry I should have clarified a little better. Should it be placed in the header collector or close to the merge? or at the bend?

Thanks,

If you just do one I think they want it at the merge. I twin widebands then in the header collector. Closer the better.....
