Gumby, you've got it right. Just keeps your EPA happy by providing O2 to assist in burning any unburnt fuel etc. I've blocked mine as I didn't like the Staintune popping on decel. Of passing interest, and known by some on this forum, is that the OZ models have an IEV built into the OEM can. I also deactivated this when fitting the Staintune.
