Right in an X pipe would likely be a good place for it, but
I wouldn't bother to put it in an H pipe, I don't think you'd
get a proper sampling there - not enough exhaust flow. I'd put
the sensor in one of the main legs before I put it in an H pipe.
In an X pipe would be ideal though, since it would see all of the
exhaust, and from both sides of the engine.
If you do go the X route, it would be a good idea to keep it
as close to the engine as practical. Assuming that you are using
a stock O2 sensor, its got a heating circuit built in, so keeping
it hot isn't a problem, but the further the sensor is from the
engine, the longer the lag time between what the engine is actually
doing and what the O2 sensor "sees".
If you decide to just put it in one of the main legs, I'd
recomend installing sensor bungs in both legs. That way,
you can swap the sensor later if you want to, and you can use
a plug to block off the other bung. That's what I did for the O2
sensor on my (aftermarket) EFI'd Barracuda. This way, if one side of
your motor runs leaner than the other, you can install the sensor
in the lean leg for safety. Or, you can install an aftermarket
O2 sensor (wide band even, if you want to), in the other leg for
an additional gauge inside the cab, or during dyno tuning, you can
use the spare bung for the wide band sensor and not have to remove
the stock sensor.
