I note that CycleX is offering stainless or mild steel 4 into 4 headpipes. On their website, they have a photo of a bike with those pipes and their "vanilla" ,pattern# 14 mufflers. The setup is a reasonable facsimile of stock cb 750 exhaust. In my view, the raison'etre of these machines is the sight of 4 exhausts from the back. Has anyone tried this setup?
