Thundercone
I'm happy with the performance of my 2018 CVO Limited but would like to get a better sound. I loved the Thundercone Slip Ons I had on my 2009 CVO Ultra. I eliminated the CAT by replacing the header with one from a 96 CI.
I'm wondering if I replace the stock slip ons with Thunderheader Chrome Thundercone Slip-On Mufflers - 1066, will I need to re-tune? What is the danger in just replacing the Slip On and nothing else and not re-tuning.
