I did a recent Weber swap, and I'm considering removing the ASV system. I have a question though that needs some expertise or previous experience. Will removing the ASV system hurt or damage my Catalyst converter? I wish I could remove it, but certain local laws prevent me from doing so. My understanding is that the ASV system pulls fresh air from the air cleaner into the catalyst converter. Will closing off that fresh air source hurt the catalyst converter? Has anyone done a weber swap on an EA 81 and not remove their catalyst converter, but did remove their ASV?
