Sounds gorgeous. I know it's an old video but please, can you tell me if the bike needs a reflash after installing this exhaust from Mivv? I would like to install one exactly like yours, my bike is a 2006 model with oxygen sensor and I am afraid of having problems with the fuel/air mixture because the original muffler with the catalytic converter will be discarded. Some say you need a reflash if the original catalyst is removed. What is your opinion, did you have any issues when using this exhaust? Thank you
