I have been researching online for a slip on exhaust. I have managed to find a few that have sound files so I can listen to them. So far, the Two Brothers has the best sound, deep and throaty. It also seems to offer a decent HP increase for a slip on. What I have not been able to find is if there is any information on how loud the pipe is. I want it to be louder than stock but I don't want to be painfully loud. Anybody have any experience with how loud this pipe is? Anybody know what decibel level is claimed for it? Any observations appreciated. Thanks.
