Thanx, I like the D&D alot. It is real loud, I like the look and the sound is nice and deep. I do worry about it being too loud though. At times when those butterfly valves open up just right I wonder if it is bothering someone who may be riding with me. I will say this though. Since I have put it on I have not had a single person try to come over on me on the freeway or highway. If you like loud D&D is for you. I put a Wolf on it before, the only one I thnk I don't like is yosh. They sound to High pitched to me.
