Wideband install on LS400

[ca12los]

I am about to install an AEM wideband gauge in my ride, and It says to put the O2 sensors 18" downstream from the exhaust.
Now on the LS or SC would this be possible???
What have some of you guys done with your setup??
Thanks in advance,

Yes its possible. I installed in my left side of the driver area. I used an older Mustang single pod pillar.

Thanks for the advice LEX...Great site!!!!
I ended up installing it on the passenger side CAT right before it get filtered. Hopefully there will be no problems in the future with it. The Gauge seems to be marking accuretly so far.

do you just need 1 or do you need one per bank?

Ideally you'd want one per bank, but for a few of my customer's cars with V-series engines, we placed the o2 in the y-pipes

cool do you place them before or after the center cat?

before cats if you want the most accurate reading. I like Ihiryu's y pipe plan, as it makes better use of the 1 sensor. You could relocate the cats a few inches down stream to allow a piece of straight pipe between the stock cats and manifolds and then place it there. If you can deal with spending about 400 on 2 sensors, this would give you the most accurate setup. 1 day bought my first sensor and installed 1 side, the next month I bought the other side due to the double price. A single sensor is ok, but remember that your blending the afr of both banks together so if an injector one 1 side sticks open, it wont be as obvious on the display. Having the #2 sensor/display wil be almost like a flashing light when you know both screens should be identical when the engine is running properly.

currently im not running the front two cats im only using the one in the y pipe section, so technically if i go ahead and do this i can use the bungs that already exist for the secondary 02 sensors

It doesnt get any easier than that! That will work perfectly.

awesome! now is there a single unit that will let me hook up 2 sensors and display them both?

I'm about to get a wideband but can only afford one at the moment so on a stock soarer manifold is there a particular side I should put it on or does it not really matter?
