Hey guys so I don't have the tape measure I need but is there an off chance that someone knows the diameter of the exhaust inlet on the stock muffler system of my 2011 650r? I found a knock off exhaust for my bike on ebay and wanna see if it matches up. Says its 60mm inlet diameter and says its a perfect replacement for the oem muffler. Thanks
