My car is going to be tuned soon and I was wondering how AEM wideband should be installed on my stock factory exhaust.

At first I thought the o2 sensor supplied with the wideband would replace the factory sensor. If this is correct everything should be simple and good to go.

If this is not the case what would my best option be? Just have a bung welded and mount the o2 supplied with the wideband in a different location?

Thanks in advance

 

This is correct. Typically you would run it in your cat delete pipe closest to the header collector. But if your going to run your cat still, you would need to put it at the header collector.
