I hafta agree, while loud pipes on Harleys might gain you the attention of other drivers - with these motorized bicycles I don't think the "pissed off chainsaw" sound is gonna do much but raise the eyebrow of the local popo.
I've done what I could to quiet my bike if for no other reason than so I
can hear lol
If you want yer bike to be loud, fine - but don't kid yerself. I seriously doubt that it'll be loud enough
to be noticed by the sheeple, or provide safety if it does.
They'll probably just steer into you anyway, wondering where that noise is coming from
