The most ideal is one on each side, close as possible to the heads to get the most accurate mixture.

That’s pretty much the same place that I mounted mine. Seems to work fine (IMG:style_emoticons/default/beerchug.gif)

I would have recommended the opposite side, as far away from the actual tailpipe that you can get, especially if you are trying to do any tuning with it. What I have seen with the sensor close to the tip like that is fresh air makes its way back in the tailpipe at idle/lower speeds providing invalid readings.
Stock style mufflers are really not ideal for getting good readings from a wideband. If you are doing actual tuning (aftermarket injection etc) rather than just installing a gauge I would recommend picking up a used Bursch or something else with a collector before the muffler to use while turning and then swap back to your stock exhaust when done.

I would 100% agree with the above. BR Frank |
