I’d like to change the muffler on my 2017 R NineT Racer from the stock one to the Vance & Hines one:
Compliment your Ducati's Desmodue engine with a look and sound that is sure to turn heads.
I’m just wondering if this will require a retune even though it’s just the muffler. I’m going to leave the headers and everything else alone.
I’d appreciate the insight.
