cat-less header and o2 spacer

anyone have any luck with using a o2 spacer to keep a cel from coming on when using a cat-less header?

looking to get a header and dont feel like paying out my nose for one.

My cel comes and goes. It was constant until we opened up the spacer a little more. Just a little more opening and it should be good to go.

once you have the code and has adapted, you'll need BMW scanner like Autologic to get rid of it. My Scangauge II can do it but hit and miss. Anti-fouler spacer is not 100% guarantee against CEL due to high flow cat.
