Technically, no xpipe will cause a CEL since it is after the primary cats. But I think you are asking about the full setup -including primary cats and xpipe. Active Autowerke claims that their system does not cause a CEL. However, I asked them what testing they did to make that conclusion (in their thread), and never received a response. The system just came out, so it will take a while for experiences to start rolling in...
