i have a renegade silencer on my bike and i have to admit it is not over noisey,but as i live in a close residental area im fitting a standard silencer as i leave for work at 530am and dont want to upset too many people as some are old and some have young children,when funds are available i will get a better can and keep it legal,my vfr750 actualy sounds very nice with the removable baffles out and not over noisey,my firestorm used to set car alarms off,when i first got the firestorm i had art cans on it,i rode into a small town with narrow streets with a police car behind me,that bike was loud but i never got pulled on it
