Doesn't work...
I installed this exact O2 spacer for a client of mine running a catted DP on the 2.0T motor. Within an hours time of driving, he had a CEL. The code was for "too restrictive airflow". We even tried to drill the holes larger to improve airflow and still, no luck. The only way to avoid a CEL, is to run software which can code it out.

From my experience they sorta work in test pipes but not in hi flow cats

I can’t seem to find the thread that actually leads you to which ones actually halfway decently work.

Vibrant J-spacers have been generally successful based on all the threads I've seen discussing cat-less exhaust options.

Do you know if people were more successful with just the 90 by themselves or with the different size restrictors that come with ithttps://uploads.tapatalk-cdn.com/20191021/4daff6cc1ac4804da52dee372d88f1fe.jpg

It's been a while since I last read about them, but IIRC I believe folks were having success with the medium sized restriction inserts.
