wanted to go with the yosh on mine because i'm not a real fan of the short pike sticking out of my 600 but the more i read the more i might go with something different.. heard some good things bout 2 bros... but still nto sure either
I have an ARROW system and love the sound.
During a dyno run where they were pulling bikes one after another and there were a lot of Yoshimura systems and M4's and various others. When mine was up and everyone was standing around talking. When the bike hit about 9000 rpm the sound changed and everyone turned around to see what it was. I got a lot of nods for the high rpm music from the ARROW.
