I just recently acquired a low mileage garage queen (2005 CBR1000RR) and the previous owner had installed a Yoshimura RS-5 slip-on. How do you tame the sound level? I searched YouTube and found that even with the Low-volume INSERT (which I have), it will only knock off 5-10% of the sound. I noticed that when I test drove it nearby (driving at speed limit), pedestrians would turn around to look at me, mostly due to the sound. That's too much unwanted attention and I feel like I'm violating their air space. I'm pretty certain, I would be harassed by police here if I were to cross their paths. Any idea how to lower the sound besides uninstalling the exhaust and get a factory version? Is the factory version also very loud?
