Haven't heard a Hawk exhaust yet around here sorry...I went with speacial ops exhaust (along with other mods and tuning) myself. Have had it for about two years and am still very happy everytime I start the her up. If Hawk is just a gutted out stock muffler then can't imagine they sound that much different. I did keep the servo intact. Where you at? I work for city of Renton and live in Seattle (Northgate). If not interested in a sound clip...would love to get another Buell buddy to ride with Fish.
