Well I got the barons 424 mufflers on and I have the whine,but I'm having too much fun with the loud exhaust to care. The video does not do the mufflers justice, They are LOUD. I'll try to put the go pro on the saddlebags and see if it will demo the sound better. I'll post when done if anyone is interested. I know I like watching videos with the sound of the bike not music.
