O2 sensor placement on a Banana can Options

[aircooledtechguy]

So,. . . My header/muffler system on my shop-car works flawlessly and actually sounds really good too. However, I REALLY love the sound of the Porsche banana can muffs. So I'm thinking of converting my shop-car to a banana can muffler. Switching could also eliminate the occasional dragging of the muffler coming out of steep parking lots. The big issue though is where would I end up mounting the O2 bung so it will read correctly?? I'm thinking that with a muffler like this one below, over on the right side (closest end) near the end would be a good spot. . . What say you??

I've already got a wide-band sensor (LC-1) that is mounted @ 12 o'clock immediately after the collector and it works great. I don't see it possible to get one mounted on the outlet though since it's got to be around 12"-15" from ambient air or it begins to have bad readings too. This is the current set-up:

that's a nice setup, the collector looks like a perfect place for the sensor. Too bad with my Dansk I can't do the same. I suppose if I were to get real serious the PLX sensor module can accept up to 32 sensors, so one on each of my four exhaust pipes would be the ultimate. Since I'm running a stock L jet system rather than carbs, I'll pick a single tube about 12 inches from the exhaust port and see what I get. Here's the specs on the PLX sensor module:

The PLX Air Fuel Ratio Sensor Module accurately measures the wideband air fuel ratio (AFR) of any internal combustion engine. It comes with a Bosch LSU 4.2 wideband oxygen sensor. Up to 32 Sensor Modules can be daisy chained together from the PLX iMFD line for modular tuning and can be connected to any PLX Multi Gauge through the digital serial output port. This Sensor Module can also be used as a stand alone unit capable of interfacing with third party hardware where both the digital output and the analog output are available simultaneously. The SM-AFR works with gasoline, bio diesel, ethanol, methanol, E85, LPG, and CNG. Advanced soft start technology prolongs the O2 sensor life. The SM-AFR never needs to be calibrated and is accurate to 0.1 AFR with a tuned critically damped controller circuit for an ultra fast reaction time. The SM-AFR has a effective measurement range of 0.68 - 1.36 Lambda. It is also capable of reporting lean readings all the way up to free air with a DM-6 Multi Gauge.
