I'm still trying to figure out how to work the video function on my camera. Plus from the videos I've heard they can be hard to get quality sound out of. So I'll describe it k?
It lacks the deep rumble of the twin which isn't great, it is slightly quieter than cans, basically sounds like 2 XR400 dirtbikes with stock mufflers. Power seems to be less on top but increased low to mid response. Good for the street. I'm still tuning the sound and performance by drilling small holes to let them breathe a bit more. Once I can test it at the track I'll determine if it was a worthwhile mod or convert back to a can configuration.
