Wide band O2 sensor location

Where would one weld a bung for a wide band O2 sensor?

I would like to do it when they do the exhaust.
- Stock manifolds
- Dual into cats into dual muffler tru-x-type internal
- Dual out all the way back
--doesn't matter from here--

I thought about into the muffler itself, but that would not be in direct flow.
 
I installed mine just before the catalytic converter on the driverside downtube (right after the header collector).

Be aware that at such a location, the sensor will have a tendency to overheat during WOT pulls unless you add some sort of heat sink to the mounting location. If you check with innovate, they have a special bung adapter that will help keep the sensor cool. you could also fabricate something.

If you don't have cats, you can put the sensor further down stream in the exhaust tube.

Make sure they test fit the exhaust before welding on the bung. You'll want to have a chance to tweak the location to make installation and removal of the sensor easy as well as provide sufficient clearance.
