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...
