I agree that the WOLO seems pretty large and obtrusive, but I like it for what it is. We're not going to get that much sound from a horn as small as the stock one. Unfortunately, Yamaha didn't leave us a whole lot of open space to work with. Heck, I can barely fit my insurance card and registration under my seat!!! I've searched through ALOT of horns, even thinking outside the box and browsing through automotive applications. The biggest sound comes from the bigger horns, it's simply a matter of compromise. Has anyone considered the space below the front of the tank, at the part where the frame meets the fork (???) Sorry the verbage escapes me tonight. Anyway, that is where I was thinking for a dual install, with my only concern being my own hearing!!!!
