hello all. my son just got an 01 blast with the vance & hines exhaust and being a new rider i would like to find a quieter end cap for this pipe. sounds great as is but a little to distracting for a newbie. will make my own if i have to but i`m getting lazy and would just as soon buy one. an help would be much appreciated. by the way, what a great bike this is but man does it shake, not at all like my old sr500.
