I'm faced with similar dilemma and so far I've come to the conclusion that the his burnt tip exhaust (as pictured in this thread) is the best looking one but I am not sure about its availability. I tried messaging the person who sold that exhaust but no reply so far.
I also don't like how the akrapovic looks on the ybr so hopefully someone can guide us in that regard. Although if you are in pindi try liaquat bagh road and the adjacent area as there are plenty of chances finding something worthwhile there.
Does anyone have an idea whether Yamaha have an plans on launching any new models soon?
