I'd put it in the bend between the collector and the muffler - better
than the tailpipe side when you can help it (less outside air
influence risk).

go ahead and install two, though - spring for the extra wideband and
bung to put on the other side.   depending on your meter you might be
able to wire both in and switch between them - else wire in a switch
on the signal wire - going to be critical when tuning duals.   less
critical when doing a single or EFI, but it's really easy to get one
bank wrong with duals.
