Wideband O2 Sensor location advise

That's some great info mattax... I appreciate it.

I'm going to clean up my exhaust between the header flange and mufflers. My X-pipe is "homemade" by the muffler shop I took it too. I have never been real happy with it.

I bought a new Flowtech X-pipe in which looks like it will flow better and two Hedman Oxygen Sensor Reducers.
Also bought one Oxygen Sensor Bung to plug up one of the O2 outlets on the reducer.

After finding the reducers ... this answers my question about where to put the oxygen sensor. :rolleyes:

I will switch the O2 sensor back and forth and see how they read on each side of the engine's exhaust.
