Well... I don't need any of that fangled, hi tech, black magic, blue tooth stuff.
E.G. I have traction control on my Gen 1 Rocket .... it's on the R/H handle bar
I need to hear the R or GT next to the TFC to see what difference there is. I think my TFC is loud enough. Could I use more power? Of course, but not more noise.
What you need to realize is that the "Mufflers" that you see on the side of the bike, are not "mufflers"
They are stylized covers that cover the welded on exit pipes from the "Box" underneath.
