I think they have a great sound too. And while you set off an alarm or two, they still have a mellower rumble (which I like) than some with a loud rumble. Perfect IMHO .Rscotts1 said:Just got back from a ride after installing my new Cycle Shack slip-on's. Man, I love these things!! Awsome sound!! Set off a few car alarms (not on purpose) in the process. Later dudes.
