I have a 2015 F3-S. My wife and I decided to put a 2 up shock on it. It seams to ride just fine. The reason we got that shock is because, when we ride together we always have the exhaust rubbing the ground. What is the best exhaust to put on the bike? The stock pipe points at the ground and, when I get on the bike it is closer to the ground. When the wife and I are on it at the same time, it is even closer. I would like an exhaust that sounds close to the stock one but, dosen't point at the ground like the stock one. I have seen the 2 brothers exhaust and it appears to fit the bike better than the stock one. What should I look at?
