After reading that members are putting back on their stock exhaust because they are not happy with the high dbs of their aftermarket exhaust I was wondering if any can compare or share their experience with aftermarket exhaust that have acceptable levels of noise. Sounds like the Yoshi and 2Bros. are loud. I know there are videos for other exhaust but that doesn't help a whole lot. If anyone has heard some of the other exhaust in comparison to those it might be extremely helpful to alot of us who are considering a new pipe. The M4 and Arrow look like possible alternatives if they are not quite so loud????
