I'm 99% decided on viper2 replacment of current pipes; but have lingering reservations about single wall, no heat-shield construction. I understand from talking to doug at fuggin the internal ceramics can knock off as much as 150 degrees outside temp, but I'm wondering about leg placement ... I mostly ride jeans and workboots, but in really muggy midwest weather I like to ride in work shorts - any trouble with shins/ankles etc. brushing up against the pipes, MORE SO than in any other set of pipes? Any feedback much appreciated ...
