The Two Brothers exhaust... We had it on the RT and looooooved it. Most of the folks that ever listened to it commented on how "Just right" the sound and sound level was. It seemed to please the majority by a wide margin.
That said. Even folks that are not fans of exhaust (Prefer stealth) found themselves drawn to it.
Now I have not yet heard the dual in person, and it is my understanding that we will be one of the first to get this newer version of the system. We are going to be "Ambassadors" of sorts. So we plan to do a little review along the way.
We purchased the new
Top Tune kit as well and plan to find the best solution for sound and sound level as we did with the RT.
At the end of the day, personally, I cannot own a new (Non vintage) motorcycle with a wimpy sounding system on it. That is like buying a sports car and having a Honda civic exhaust on it... nojoke Of course I am not a fan of the "To Loud" systems, but I am of the "Just right" systems.
