For those who have one or what one, I received my exhaust and found it had a hole in the pipe for an O2 sensor. I got the supplier, sporttour.com (good service and prices), to check into it. After some calls on their part, they found that Leo Vince was unaware that the US models did not use an O2 sensor. Sporttour arranged for a plug to be sent from Leo Vince. 12 days later a nice O2 plug arrived from Sporttour.

Yes, and I understand that the Remus cannister I have ordered also has that sensor hole. But I was told that a plug comes with the muffler. Must be a European model requirement to have that sensor.

By the way. Do you have to cut off the stock muffler in order to install the Leo Vince? It appears that the muffler, exhaust pipe and headers is all one welded unit on the 650...

It comes with a separate pipe. The exhaust slips on the pipe.
