O2 Spacer

mahsan988 · 05-12-2023, 11:34 AM

Hey everyone, I have an N55 M2 with the Fabspeed high flow cat and it has had a CEL and I need to get an inspection in MA. (before you ask, I bought this unit used and was told it threw no lights but it did... have reached out to Fabspeed and they will not help).

I want to get an O2 spacer and was wondering if there is enough room to get a straight spacer or do I need to get an elbow style?

Any help/suggestion is greatly appreciated!

In my experience, O2 spacers will not work on this car - I tried one and it almost immediately threw a CEL. You'll have to tune to get the CEL but either way you won't pass emissions testing. I'd pick up a used cat if I were you and just swap it when it comes time for inspection
