I had a scorpion on my K5 for 2 years with the baffle removed.......No problem just don't cane it everywhere and draw too much attention too yourself. I pulled up next to a meat waggon once and plod stuck his head out and said "that sounds much bigger than the bike is, nice one". You see, if you don't make childrens ears bleed in the high st. But give the odd knob end car driver a quick blast to let him know you're in his blind spot, that's fine by me and considered safe by all my plod mates
