I'm trying to make a downpipe, the only problem is I need an O2 housing. Is it possible to weld the existing O2 housing on my custom one. Or weld some nuts to the downpipe for the threads? I heard of someone hear saying something about spark plug fouler?

I need ideas here, thanks.

Any muffler shop should be able to make you an O2 bung. they could probably just cut a hole, put in a steel coupling of some sort, then tap it to fit the O2 threads. shouldnt be too much $$$ either.

I used a spark plug fouler for a ford... It has the thread pattern we needed.
When you look at the fouler you will be able to see it is a little too deep, and at the bottom of it there is a cup with a hole. Cut the cup off the bottom, and put it in your downpipe :P

Edit: 2 foulers cost $3 at pep boys.
