I'm finding that the loudness of the pipes is all relative. The stock pipes are not loud. I think we can all agree on that. The V&H Long Shots on my RK were pretty loud, but not like some others that completely drowned out the sound of my bike. When I got the Fullsac 2.25" baffles put in, I thought that they were just about right. Definitely not nearly as loud as the V&H. On my last ride I took, now the Fullsac's are even sounding a bit loud to me. As I'm typing, I'm sitting here thinking about how much louder they seemed to be, and I'm thinking that maybe something is burning out inside and they are just coming into their own, as far as what they will sound like. Then it just hit right before I typed that last sentence. The last time I rode, I was wearing a half helmet versus wearing a full face before. Duh! No wonder they sounded louder now.
