i am using the vivi on a kgo. i like it a lot. but it does not look good. i need someone to point me EXACTLY to a sleeve or cone or whatever it is called to make it look good again. also ,one that does not impede the performance. i have seen a lot of links, but when i get there , it does not say it is for the vivi and kgo. tired of buying stuff that is wrong when i get it.....thanks......vince
