selling a stainless steel decat mid pipe for a yamaha R1 2009-2014. I bought the item as it was attached to a set of Acropovic end cans that I wanted. The item has a second lambda sensor port welded to it, the purpose I don't know, it works well enough. Item is some sort of stainless steel as is attracted by a magnetic but only very slightly so probably titanium steel alloy, not sure though.
