I put a photo of the SuperTrapp silencers in my Photo Gallery at
http://www.bonnevilleamerica.com/photopost/showgallery.php?cat=646 I'll try to find a way to leave a hotlink but it's under Silvergator. I liked the sound and both owners with SuperTrapps reported that the bikes seems much stronger. Unfortunately, I like the looks of the stock slash cut pipes better but I might go with the SuperTrapps anyway. BTW, my bike is in the background.
