I want my motorcycle to sound like a motorcycle and not some government mandated sewing machine. My Tiger has the stock exhaust, but will probably replace it with a Blue Flame to get that nice motorcycle rort sound. I have little use for people who point their collective fingers at my bike and proclaim "Noisy Noisy Noisy" and then load their family up in the SUV and attend a high school or college football game, yell , scream, bang crash cymbals, and beat bass drums for hours on end and generally ruin my quiet Saturday mornings in the yard with my dog with their "noise".
