o2 sensor location - does it make a difference? And bushing hell!

The weld-in bung for the O2 sensor is a cheap item, any muffler shop can add this for you... (If you do, have them put it such that you can remove the 02 sensor from above... much easier...)

The only disadvantages to moving it down to the cat are making the wires reach, and if you have an older unheated 02 sensor, waiting longer for it to heat up...
