This off season we purchased some stainless merge collectors and they don't have a bung in them. We had already welded a 2nd bung in one of the primaries about 6-8 inches before the collector. So for now to get the car running that is where the O2 is.
We want to experiment a little with and without the Xpipe. So I guess Ultimately I have 2 questions. Will putting a bung in the collector just after the merge affect the effectiveness of the merge?
Second, I assume when not running the Xpipe or any additional extension after the new merge collector having the O2 in the collector is going to cause some issues with being too close to fresh air. Where do most of you run the O2? I was also thinking just running in a single primary wasn't an effective strategy either..

You do not want to put the O2 sensor on the primaries.
Here is some good information.
