I just purchased a used Kerker Supermeg exhaust, I was told it would fit Harley Softails from 2012-2017 models. The only part number I could find was stamped at the rear of the 2-1 headpipe where it would attach to the muffler. The number is 050-7691 19113. Can anyone confirm that this would fit 2012-2017 Softails? thanks
