I have the same on my Roadking Classic. I only have 7,000 miles on mine, but they do sound better when the get warmed up. I was trying to descide on putting headers on with them. Was thinking V&H dresser duals or power duals. Not in love with the look of the power duals. The "X" is not really what I'm looking for. Like the look of true duals. Any suggestion to help me deside.
I have the same ones on my '14 Ultra and '09 Heritage Classic. The Heritage is much louder with a nice bark to them. The Ultra sounds good, but not as loud as the Heritage, not sure why.
