I hate to post such a simple question but I was hoping to get a quick answer before I drop my downpipe off to get a bung welded in. I have Megan resonated downpipes with the 02 sensors in the stock location. I need to put a bung for my AEM Wideband O2 sensor and was planning on placing it a few inches in front of the driver's side stock 02 sensor location. Any suggestions? Thanks in advance.

 

Well I'm just going to put it there (there is really no other place to put it) and try to have them angle it downward a little bit so no fluid collects in the sensor.

 

Just as long as you make sure that the angle of the bung won't cause the o2 sensor to be pushed up against anything when installed.
